CYBERNETIES BASED AUTOMATIC IRRIGATION SYSTEM USING IOT

The main objective of this work is to control the water level for irrigation remotely through internet and also to optimize the usage of water resources in the process. The method employed continuously monitors the soil moisture level to decide whether irrigation is needed, and how much water is required in the soil. A pumping mechanism is used to deliver the required amount of water to the soil. A moisture sensor is constructed to model the electrical resistance of the soil; a regulated 12 volts power supply unit is constructed to power the system; the control circuit is implemented using Node MCU board; and the pumping subsystem, consisting of a submersible low-noise micro water pump is constructed using a small dc-operated motor. Then it can be operated through Google assistant, mobile phone, website link, #tag post in FB
