Design of intelligent irrigation and soil loosening system for Agricultural Internet of things

Aiming at the problem of soil hardening, an intelligent irrigation and soil loosening system is designed. This design uses Arduino microcontroller as the controller. The microcontroller analyzes and processes the humidity value detected by the soil humidity sensor, and displays the data on the LCD screen. When the humidity value is lower than the lower limit value, irrigation and soil loosening are carried out, and irrigation and soil loosening are stopped until the humidity value reaches the upper limit value. Through the Bluetooth communication with the mobile phone, users can see the real-time humidity value on the mobile phone, and control the switch of the water pump, the depth automatic adjustment mechanism and the execution of the soil loosening mechanism through the buttons on the mobile phone. The design is intelligent, saves water resources, saves labor, and improves crop yield.
