Design and Development of Electronics Pest Repellent Using PIR Sensor and 8051 Micro-Controller

Rodents and pests are a huge problem in our daily lives and in the industry and getting relieve from them seems almost inevitable. They cause large scale damage to our crops, commodities and other useful things. Pest repellents already exist, but due to their toxicity or high price, they aren’t feasible to use. In this paper, we have been able to design an Electronic Pest Repellent circuit using PIR sensor and 8051 micro-controller module, which prove to be lower in cost than the pre-existing electronic repellents. The frequency generated by this setup makes the environment unpleasant for the rodents and pests hence they evade the premises. This device can be beneficial to farmers, storage godowns, general public to repel these harmful rodents and pests.
