Solar powered smart ultrasonic insects repellent with DTMF and manual control for agriculture

The paper represents a smart gadget to avert the calamitous effects of pest bugs in the farming land as well as in household commodities. In this paper, development and performance analysis of smart ultrasonic insects repellent device has been demonstrated. This device is able to generate different types of frequencies which are very helpful to repel different types of insects. It can be controlled from any distance with DTMF (Dual Tone Multi Frequency) technology. Besides, manual control with night mode via LDR (Light Dependent Resistor) has also been employed. The device would be charged through solar energy system which is a cost effective approach. A power amplifier along with a microcontroller known as Arduino Uno as well as solar charger circuit regulator and solar panel are used. The implementation of this device in farmland has shown a great reduction of bugs attack compared to the other land which doesn't have one.
