Solar energy driven Arduino based smart mosquito repeller system

Mosquitoes and other insects are harmful for humans as they can cause many diseases which are harmful for human health. In order to avoid the mosquitoes, people use chemical repellents which affect the environment adversely or mosquito repeller skin creams can create skin problems. This paper proposes the smart ultrasonic insect repelling system driven by harvesting energy from solar panels. The ultrasonic waves have frequencies more than 20,000 Hz which are inaudible to humans but when insects come in the contact with ultrasonic waves, they sense the waves from special hair or sensilla present on the antennae of mosquitoes which will create stress on the nervous system and jam their own ultrasonic frequency and force them to leave that area. The frequency ranges of 38-44 kHz can be used effectively to repel the mosquitoes and flies. The system employs solar panel as energy source to charge the rechargeable 12V battery which is used to drive the Arduino UNO to turn on and turn off the mosquito repeller system. The proposed smart mosquito repeller system can be used to repel mosquitos from within the area of 125 square meters.
