The proposed system consist of pesticide mixer which automatically mixes the pesticide and water in particular ratio and the mixer is automatically sprayed to the field on the programmed date with the help of PLC. This system will also be useful in monitoring the soil moisture condition and level of the water in the field via moisture sensors and ultrasonic sensor which is connected in the transmitter side of the RF module. The system proposes a soil moisture sensor and ultrasonic sensor at each place in the field where the moisture content of the soil and water level in the field has to be monitored which is powered by solar. When moisture content in the soil is low or water level in the field is below certain level, the transmitter RF sends a signal to the receiver RF and accordingly the motor is turned ON/OFF with the help of PLC.Keywords—PLC, nrf2L01 module, Moisture sensor, Ultrasonic sensor, Pesticide mixer, solar 1.INTRODUCTIONIn today’s world, agriculture and technology are the backbone of economy. Agriculture plays an important role in the economic development of the developing countries. Technology guides the economic prosperity of the developed countries. Agriculture should yield double the current food production by 2050 as the global population is expected to reach 9.6 billion people. Climate change will have a huge impact on agriculture which includes extreme weather conditions, intense storms and heat waves, floods, whilst water shortages in certain parts of the world could become critical.
