Abstract: Every year, farmers in Bhutan lose their crops to wild animals, and it has remained as the same problem over the years. Farmers and Government of Bhutan struggles to get rid of this problem. In the western part of Bhutan, the major crop damage is done by wild pigs. This study was carried out to see the feasibility of using Passive Infrared Sensor (PIR) to protect crops from wild pigs. PIR sensors are motion detector sensors and operates 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 sensing unit, and an alarm unit comprising of a lighting and an audio system. The sensing unit make use of PIR sensor to activate the alarm unit. The audio system is recorded with the sounds that our farmers use to chase away wild pigs during the night hours such as beating of the drums, dog barking etc. The sensor gets activated producing an electrical output which triggers the alarm unit turning ON the light and the audio system.
