Electronic Mosquito Repellent Circuit Diagram. The heart of this circuit is a ne555 timer ic. Various mosquito repellent solutions like coils liquid vaporizers and creams all have possible adverse effects to health.
Various mosquito repellent solutions like coils liquid vaporizers and creams all have possible adverse effects to health. Here is the circuit diagram of an ultrasonic mosquito repeller the circuit is based on the theory that insects like mosquito can be repelled by using sound frequencies in the ultrasonic above 20khz range the circuit is nothing but a pll ic cmos 4047 wired as an oscillator working at 22khz a complementary symmetry amplifier consisting of four transistor is used to amplify the sound the piezo buzzer converts the output of amplifier to ultrasonic sound that can be heard by the insects. In the circuit connects two transistors q1 q2 into a bistable multivibrator oscillator to generate a sound frequency.
The circuit will require just 3 volts which may be supplied using a button cell that should last ages.
The heart of this circuit is a ne555 timer ic. Various mosquito repellent solutions like coils liquid vaporizers and creams all have possible adverse effects to health. Then there are electronic mosquito repellents available in market which are equally efficient and relatively safer. The circuit will require just 3 volts which may be supplied using a button cell that should last ages.
