Abstract: In our country 70 to 75% peoples are dependent on the agriculture field. Irrigation is one of the basic need in agriculture field. But now day’s improper irrigation system is most of the big problem is in front of farmers. So avoid this problem we need to accept new technologies such as smart irrigation system. That’s why me and my group members are select the topic “Smart irrigation system for agriculture field monitoring for our BE level project. The Smart irrigation System has wide scope to automate the complete irrigation system. Here we are building a IoT based Irrigation System using ESP8266 Node MCU Module and DHT11 Sensor. It will not only automatically irrigate the water based on the moisture level in the soil but also send the Data to Thing Speak 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. We previously build similar Automatic Plant Irrigation System which sends alerts on mobile but not on IoT cloud. 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. So in this tutorial we are using such a crop which will require soil moisture of about 50-55%. So when the soil loses its moisture to less than 50% then Motor pump will turn on automatically to sprinkle the water and it will continue to sprinkle the water until the moisture goes up to 55% and after that the pump will be turned off. The sensor data will be sent to Thing Speak Server in defined interval of time so that it can be monitored from anywhere in the world.
