This Electronic Mosquito Repellent Circuit Circuit is very easy and very simple. This circuit has minimum components to repel mosquitoes. A large number of things like creams, coils, oils, and other things are available in the market to repel mosquitoes.
At the same time, all these replant can become the cause of many diseases like skin cancer and etc. Creams and oils become the cause of skin diseases, while mates and coils produce toxic fumes. Toxic fumes can lead to serious breathing problems. Electronic Mosquito Repellent circuit is not harmful for human beings because it produces frequency that human beings can not hear. Mosquito repellent circuit generates a frequency from 20-38 KHz. This range of frequency irritates mosquitoes and they run away from your house.
Circuit Diagram Electronic Mosquito Repellent Circuit
Complete circuit diagram of mosquito repllent circuit is given below and also used components of circuit are also given in the list.
Principle Behind Mosquito Repellent Circuit
Human generations are able to hear frequency range from 20Hz to 20 KHz. The frequency above this is not hearable by the human generation and this frequency is called ultrasonic frequency. Many animals and insects are able to hear this ultrasonic frequency.
I want to clarify that in mosquitoes ultrasound is generated by the male mosquito and the female receives that sound after breeding female mosquitoes mainly avoid this frequency. This circuit produces the same frequency as the male mosquito generates and these create stress on the female mosquito and they run away from this frequency.
Components Required Electronic Mosquito Repellent Circuit
- 555 timer IC
- A ceramic capacitor of 0.01 MF
- A resistor of 1k
- Piezo buzzer
- 10k variable resistor
- A 9V battery
Transistor and ICs can be used to generates these frequency. we have to connect such type of buzzer with the circuit that can generates the ultra sound. We have used a 10k variable resistor to increase and decrease the range of frequency.
- Assemble the circuit on a general purpose PCB for better result.
- The circuit can be powered from 9 to 12 volts DC.
- The buzzer can be any general purpose piezo buzzer.
- The IC should be mounted on pcb or in holder.
- change the frequency at higher rate.
