The research work was under taken on “Development of Solar Powered Ultrasonic System for Farms.” A Solar powered ultrasonic system was developed consisted of 10 W SPV panel, 12 V; 7 Ah lead acid battery, 8051 microcontroller, PIR sensor, ultrasound and adjustable stand. This study was carried out to see the feasibility of using Passive Infrared Sensor (PIR) to protect crops from birds and animals. PIR sensors are motion detector sensors and operate based on the infrared radiation from the body. The sensor has the advantage of low cost, and it is used extensively in indoor automated motion detection systems. All bodies including human emit infrared radiation and the radiation amount depends on body surface temperature. The proposed system consists of a microcontroller, frequency adjuster, sensitivity adjuster, an ultrasound comprising of lighting. When the birds or animals were in the range of PIR sensor it senses the motion and it gives signal to the microcontroller which gives signal to the ultrasound and ultrasound starts vibrating.
