Project Area of Specialization Internet of ThingsProject SummaryFresh water is the most important aspect of life, yet a big percentage of it gets wasted on over irrigation in agricultural usage. Agriculture is important as well as it provides us with food for livestock and for humans to eat and prosper with.
Farmers deal with issues on a daily bases as over-irrigation and under-irrigation can demean the quality of crops on the short and long range. It is also an automatic plant watering system using simple Arduino uno board and a soil sensor and relay.
Therefore, continuous and precise monitoring is required to ensure maximum agricultural yield. This work proposes a solution that has both a conceptualized and actualized prototype of a smart irrigation system that uses an IOT approach for monitoring the moisture in the fields.
- We can monitor the values in real-time.
- Notification messages are sent when the Sensor value increases above or decreases below a certain pre-defined value.
- We use Nodemcu Module to monitor the data on the serial monitor or you can design a cell phone application and monitor the data from anywhere around the world.
- Intelligent System to maintain irrigation automatically.
- Minimize Wastage of Water.
- To give water to the plants according to their needs.
- We are able to receive the moisture, temperature and humidity values in real-time.
- Remote Controlling and Monitoring.
- We’ll receive the data and send it to the Blynk (discussed further in the next portions) application for further processing.
On the transmitter side, the Lora module is used with the Arduino Nano to send the Sensors data to the Receiver. ON the receiver side, the Lora module is connected with the Nodemcu ESP8266 Wifi module. At this point, you can design a cell phone application and monitor the data from anywhere around the world. For the demonstration purposes, I connected a variable resistor, I can monitor the values in real-time, notification messages are sent when the Sensor value increases above or decreases below a certain pre-defined value. These values are sent from the transmitter side through a Lora transceiver module, on the receiver side another Lora transceiver module is connected with the Nodemcu ESP8266 Wifi Module which receives the data and then sends it to the Blynk application. After performing all the basic tests, finally, I soldered all the components on the Vero boards and fixed the transmitter side in a waterproof plastic enclosure.
Benefits of the Project- The advantage of using the smart irrigation IOT technique is that it reduces overall water consumption.
- It’ll increase more productivity.
- Automated Plant Watering System.
- The moment when sensors provide information such as the readings of whether soil moisture is decreased or not, the LED bulb automatically lights up to notify the system to start the irrigation of farmland.
- LED light bulbs are able to indicate the current status of the soil moisture level.
- It’ll also show us the notifications on the screen of the Application whether the moisture level is well or low.
- It helps in reducing and increasing the amount of water given by sensors to control the moisture level needed in the soil for crops.
- Dashboard on Mobile application.
- A remotely controlled irrigations system.
- FEATURES:
- Supports Gravity 3-Pin Interface.
- Analog Output.
- APPLICATIONS:
- Gardening & Farming.
- Moisture Detection.
- Intelligent Agriculture.
