Build a self-sustaining plant system with realtime sensor data monitoring. Smart farming has taken the world by storm as farmers have learned to embrace the world of IoT, not reject it. As our world population is soon to reach 10 billion, we need to more greatly adopt technological, conservative methods for feeding the masses and IoT is the way to go.
We at PubNub have worked with numerous Agri-tech companies such as smart tractors, climate monitoring and many more. We have even written articles demonstrating how to utilize the power of cloud computing into smart agriculture. As for inspiration for this project, we have created this demo project that demonstrates how our real-time data infrastructure can be used to create self-sustaining botanical systems.
Simply, snip the head off of the phone adapter and strip about 5 inches of the rubber casing to expose the wires. Follow this diagram and make sure you plug in extra male-male wires to the female headers we soldered earlier to connect everything together.
Notice that we used a relay in our circuit as the Raspberry Pi can only safely tolerate input voltages under 3.
Therefore, we need to isolate our 5V power supply to avoid any damage to the Pi. The pump is a submersible water pump, meaning that it must be completely submerged in a water reservoir in order to pump water.
Therefore, for this project, you will need to leave out a bowl or any method for a reservoir next to the plant at all times. The soil moisture sensor is a standard moisture sensor that outputs a voltage when wet, and none when dry. You can adjust the sensitivity of the sensor with the potentiometer located on the sensor.
Secure Shell protocol SSH allows users to remotely access their Raspberry Pi terminals from their computers over wifi. This allows for a quicker and smoother development process. While we may have 3 devices, we only need to read analog voltages from 2 of them. The pump only needs to operate on a GPIO switch. For our submersible pump, we need to operate an output voltage of 1 or 0 from the RPI to turn it on. Conversely, the soil moisture sensor gives the RPI an input voltage 1 or 0, depending on whether it is wet or dry.
Additionally, we initialized the soil moisture sensor as a button for it will send out a continuous input voltage of a 1 like when holding down a button when wet. It will also be a good idea to set some initial conditions for when the program first boots up: a flag variable to toggle the state of the program to Auto mode or Manual mode and turning the pump off when the program boots up. To make sure we can receive messages we need to add a listener to handle the incoming messages and declare a subscription to listen in on a particular channel.
Now, we need a method to check whether our sensor is wet or dry. We now need to set state conditions that check whether or not the flag variable is a 1 or a 0 aka in auto mode or manual mode. Now we can publish that data to PubNub for future IoT use.Skip to Main Content.

IOT Based Smart Irrigation System Using Raspberry Pi
Star zigbee topology serves as backbone for the communication between raspberry pi and end devices. Raspberry pi acts a central coordinator and end devices act as various routers. Low-cost and energy efficient drip irrigation system serves as a proof of concept.
The design can be used in big agriculture fields as well as in small gardens via just sending an email to the system to water plants. The use of ultrasound sensors and solenoid valves make a smart drip irrigation system. The paper explains the complete installation of the system including hardware and software aspects. Experimental set-up is also tested and explained for an automatic drip irrigation system to water 50 pots. Article :.Irrigation system based on Raspberri PI - cheap and easy
DOI: Need Help?Farmers across the world face a lot of difficulties in growing crops because of unpredictable weather conditions and shortage of water. The traditional irrigation system uses a large amount of water and supplies uneven water to corps. This affects the quality of crops. Many farmers already start using the Greenhouse farming and Smart Irrigation System. Emerging IoT technologies and sensors are used to develop the irrigation system that can automatically supply water according to climate conditions like moisture value, temperature, etc.
It will automatically sprinkle the water to plants when the moisture value goes below a particular value. It will also send the moisture data to Adafruit IO Server to keep track of the land condition. This project uses a solenoid valve to supply the water to the plants.
You can change the moisture value at which the solenoid valve should turn on according to your plant's requirement. Solenoid Valve is connected to the relay module, so whenever NodeMCU generates trigger it will sprinkle water. Using Adafruit IO, you can upload, display, and monitor your data over the internet, and make your project IoT enabled.
For test and try, with some limitation, Adafruit IO is free to use. Copy this key and username, it will be needed later in the code. Now, after this, you need to create a feed. After this, a new window will open to enter the Name and Description of the feed.
The writing description is optional. For this project, we created a total of three feeds- for solenoid valve, moisture data, and LED. After creating feeds, now create an Adafruit IO dashboard to show all of these feeds on a single page.
As the dashboard is created now, we will add our feeds to the dashboard. First, we will add two toggle buttons blocks to control the LED and solenoid valves. And then one Graph block for Moisture Data. In the next window, it will ask you to choose the feed, so click on LED feed.
After this, follow the same procedure to create another Toggle button block for the solenoid valve. You can download the library from here:.
In Boards Manager window, Type esp in the search box, esp will be listed there below. Now select the latest version of the board and click on install. Complete code is given at the end of this tutorial, here we are explaining the program step by step so that you can easily understand the working of this code.
Set up the feed you're publishing to.Most of the farmers use large portions of farming land and it becomes very difficult to reach and track each corner of large lands. Sometime there is a possibility of uneven water sprinkles. This result in the bad quality crops which further leads to financial losses.
The Smart irrigation System has wide scope to automate the complete irrigation system. It will not only automatically irrigate the water based on the moisture level in the soil but also send the Data to ThingSpeak Server to keep track of the land condition. The System will consist a water pump which will be used to sprinkle water on the land depending upon the land environmental condition such as Moisture, Temperature and Humidity.
Apart from this, Rain alarm and soil moisture detector circuit can also be helpful in building Smart Irrigation system. Before starting, it is important to note that the different crops require different Soil Moisture, Temperature and Humidity Condition. The sensor data will be sent to ThingSpeak Server in defined interval of time so that it can be monitored from anywhere in the world.
You can buy all the components required for this project. Since the NodeMCU cannot give output voltage greater than 3. Complete code with a working video is given at the end of this tutorial, here we are explaining the program to understand the working flow of the project.
We will be using millis function to send the data after every defined interval of time here it is 10 seconds. The delay is avoided since it stops the program for a defined delay where microcontroller cannot do other tasks. Learn more about the difference between delay and millis here. Set motor pin as output, and turn off the motor initially. Start the DHT11 sensor reading. Define the current time of starting the program and save it in a variable to compare it with the elapsed time.
If the moisture reading is in between the required soil moisture range then keep the pump off or if it goes beyond the required moisture then turn the pump ON. Now after every 10 seconds call the sendThingspeak function to send the moisture, temperature and humidity data to ThingSpeak server. In the sendThingspeak function we check if the system is connected to server and if yes then we prepare a string where moisture, temperature, humidity reading is written and this string will be sent to ThingSpeak server along with API key and server address.
Finally the data is sent to ThingSpeak server using client. Note that it is important to switch off the motor when the soil moisture has reached the required level after water sprinkle. You can make a more smart system which can contain different control for different crops.

At the same time sensors are not having ability to predict the weather accurately, so we are using weather cloud to know the current weather and climate change yet to happen, like every weather information is monitored, when there are any chances of rain in weather cloud then the camera gets triggered and capture the image of the atmosphere with the data log of current weather logs and upcoming weather logs are sent to mail by the user.
And also parameters measured by sensors are sent through MQTT protocol, which having the common node, when ever MQTT client comes into the network, not only the current data log, but also the old data also sent to that MQTT client which has high speed transmission. So that watering and pesticides can be served based on the conditions of the field. In the existing system, all weather predictions and environmental change are done manually and they are using WSN for the communication, it is actually slower than MQTT so that transmission occurs slowly which also may cause a collision, when client is disconnected unexpectedly.
In this proposed system, both sensors and weather forecasting cloud is used, so that resulting data having high accuracy about the environment, also we are using MQTT Message Queuing Telemetry Transport which is very much faster than WSN. By this system all gets processed automatically, if there is any possibility of rain in weather cloud, then the current climatic conditions and upcoming possibilities of rain data log and also the current image of the environment will be sent to the users mail.
According to this system, irrigation system becomes more autonomous with quick transmission of data by using MQTT protocol. The main advantage in MQTT protocol is, even when clients are not in the node network, data will be sent, whenever a client is connected with that node, they can able to see the data which has been sent already.Parole absconder warrant

The conventional irrigation techniques have some problems like farmer should visit the field regularly even at night, then he may face some hazards like snake bite, electric shock and etc.Ssh through proxy host
In this paper a web based smart irrigation system using Raspberry Pi is implemented. The proposed system checks the temperature and moisture content present in the soil.
The motor is also automatically controlled ON and OFF, when the 3-phase supply is present in the field and also with the flow of water.
The acquired temperature and moisture content of the soil are sent to Raspberry Pi using nRF24L01 transceiver. Raspberry Pi posts the received values on the webpage.
When we enter the acquired parameter values in the soil test blogs, the webpage shows the suggestions of pesticides and crops that need to be taken by the farmer to increase the yield. The system can reduce the water consumption and wastage of water. Earlier the crop yielding was very high because the ground water levels were high. In the present day, to reduce the water consumption and increasing in the yield is a big challenge. Watering to the field is called irrigation.
Watering to the soil is mainly depend upon soil moisture and temperature sensor values, if moisture content in the soil is less than the threshold, then it indicates watering is required to the field. In the literature, few irrigation management systems are reported, which have some limitations like, watering is done to the field without analysing the soil parameters, this causes non uniform water to the field, so it results in wastage of water and decrease in the yield.
Sometimes human intervention is also required. Dhiraj Sunehra soil parameters soil moisture, soil temperature and humidity sensors, etc.Best smash moves
For that we propose a web based smart irrigation system using Raspberry Pi. The web based smart irrigation system means; farmer can monitor the sensor values and field status on the webpage.
From the webpage farmer can know the water pump status and water level in the well. We can solve those problems by using a web based smart irrigation system. So the water is uniformly distributed to the field and helps to increasing in the yield. Satya et al have proposed a water irrigation system that controls the flow of water to the crops depending on the water level and the soil moisture.
Also, the farmer receives a SMS notification about the amount of time that water is flown to the crops . Usha Rani and Kamalesh designed a ZigBee and web based automatic irrigation system to monitor the soil moisture and motor status.
An SMS is sent to the farmer about motor status . Ghosh et al used cloud computing platform, a microcontroller and an isolated server to store sensor outputs and accordingly turn on or off drip irrigation system . Namala et al implemented an intelligent and smart irrigation system for watering of flowering plants .
