Mosquito Repellent Circuit Diagram. The buzzer is driven by an oscillator circuit a 555 timer based astable multivibrator circuit as the oscillator circuit. Circuit diagram of electronic mosquito repellent circuit.
Electronic Mosquito Repellent Circuit In 2021 Electronic Mosquito Repellent Electronic Mosquito Mosquito from www.pinterest.com
This electronic mosquito repellent circuit is easy to build but is kind of hard to adjust on the exact sound frequency which will repel the mosquitoes. Pin2 is a triggered active low pin which is directly connected to the pin6 for astable operation. In the circuit connects two transistors q1 q2 into a bistable multivibrator oscillator to generate a sound frequency.
This can be done simply by replacing c1 with any other capacitor having value in between 0 02 and 0 1 uf.
