Farmers often face the challenge of guarding their cultivations from wild animals through the use of fencing instruments with high electrical voltages. Traditionally, household electricity supply or solar energy is used for fencing instruments which have their own hindrances. Solar panels are quite expensive and require tedious maintenance which can be a little overwhelming for farmers. But it is essential to avoid the man-animal conflict while protecting human harvests.
To protect the harvest from animals and to reduce the man-animal conflict, Mr. Krishnan has devised a fence with an inverter-transformer circuit which includes a buzzer kit (siren kit) in tandem with a relay circuit for standby battery. The voltage output fluctuates from 12-15 V with frequency of 20,000 Hz, which can deliver a shock but won’t cause severe harm. This instrument is rather contrary to the 230/110V 50Hz regular outputs which can be fatal to humans or animals that come in contact with it. This designed unit can cover up to 3.5 acres of land.
Scalability and Impact:
The instrument is designed to work from 6 p.m. to 6 a.m. as most of the animal intrusions occur only after dark. This setting can be changed as per the farmer’s requirement. A test was conducted with 1 unit covering 1,000 Sq. M. at a farm which was considered as the most attack prone zone in the region. 1 full cycle has been completed successfully where the potential attacks on the farms were prevented. They are planning to scale up pilot testing with installation of minimum 100 units across 10 villages to check the efficiency in various conditions and altitudes and will focus on scope for improvement.
