IOT Based Smart Agriculture System Electronics Engineering Final Year Project

This project consists DHT11 (temperature and humidity) sensor and soil moisture sensor. Two sensors connected to Arduino through digital and analog pins respectively. WIFI (Esp8266/IOT module) also connected to Arduino through UART pins. AC pump, DC fan and heaters are controlled through relays. These three control are few control parameters of Agriculture.

WORKING:

DHT11 (temperature and humidity) sensor sense environmental temperature /humidity and sends to Arduino. Soil moisture sensor sense soil moisture Dry and Wet conditions. Arduino takes all these sensor values and displayed on LCD. At the same time Arduino sends to server through WIFI (Esp8266/IOT module). Farmer can monitor all these values from anywhere. Also Farmer can control AC pump for soil moisture, DC fan for temperature and heating element (heater) for humidity from IOT server.
