This circuit generates a frequency 10-30 kHz that creates a sonic zone disturbing to mosquitoes.
A piezo board creates the frequency equal to the frequency generated by the mosquito during flight causing the mosquito to believe he/she is flying into a trap.
Technical Specifications:
- Power Source: 3 VDC
- Power consumption: 20 mA max.
- PCB dimensions: 1.60 x 1.39 inches
Operating Principles:
- Transistor 1 and 2 control low frequency 10 kHz, while transistors 3 and 4 control high frequency 30 kHz.
- This circuit is designed to alternate the frequency.
