Winter will pass quickly (we hope so) and mosquitoes will attack us again. There are many ways to deter them - we suggest using electronics. We present the ultrasonic scare off of insects, whose characteristic feature is that the signal it generates changes over a wide range of frequencies at random intervals. This approach is necessary, because even the most primitive organism adapts to the environment and subjected to constant, invariable stimuli, (which most often occur in factory devices of this type) gets used to them. And stops responding to them, which in the case of mosquitoes is not in the hand of a man.
The device is especially recommended for gardeners and lovers of nature
Selected parameters:
- frequency of the output signal - variable in the range of 20-40 kHz
- random inclusion of emission periods
- microcontroller control
- low battery voltage indication - LED diode
- TX1 ultrasonic transducer
- power supply - 9Vdc
- programmed layout
- A detailed description in EP 11/10
