MOSQUITO REPELLANT by IC 555 4017 4011
The mosquito repellent circuit employs a high-frequency sound generator, which is designed to emit ultrasonic waves that are typically inaudible to humans but can deter mosquitoes. The core of the circuit is the 555 timer IC, configured in astable mode to produce a square wave output at a frequency that is effective for repelling mosquitoes. The frequency can be adjusted by changing the resistor and capacitor values connected to the 555 timer.
The output from the 555 timer is fed into a decade counter IC, the 4017, which can be used to drive multiple outputs. This allows for the possibility of connecting several ultrasonic transducers to enhance the coverage area of the mosquito repellent effect. The 4017 IC sequentially activates its output pins, which can be connected to different transducers, ensuring that the ultrasonic sound is emitted in a pattern that maximizes the area of effect.
Power supply requirements for the circuit are minimal, often achievable with a standard 9V battery or a similar low-voltage source. The circuit can be housed in a compact enclosure for portability and ease of use. Additional features, such as an LED indicator to show when the circuit is active, can be integrated for user feedback.
Overall, this mosquito repellent circuit is an effective and economical solution for repelling mosquitoes using high-frequency sound, making it suitable for outdoor use during warm weather.This is Circuit MOSQUITO REPELLANT.
