Solar Insect Killer Circuit for Protecting Crops in Farms
The insect killer circuit presented here is designed to attract insects during night, and electrocute them through a high voltage mesh trap. The unit can be installed in farms for protecting crops from potentially harmful insects. The unit being solar powered does not depend on human intervention and works independently. In one of our previous […]
Simple Thermostat Circuit Using Transistors
The electronic thermostat explained here can be used to control the room temperature by appropriately switching (turning on and off) a heating device. By: R.K. Singh Operational details of electronic thermostat The circuit employs a thermistor NTC (negative temperature coefficient) as the sensor device. – As long as the ambient temperature stays higher than the […]
