Description

When you hit your hand 2 times, the sound sensor reacts and lights up. It will automatically turn off after about 15 seconds.
The LED lights up when the sound sensor detects an impact sound of about 95 dB or more within 1.3 seconds. (It is estimated that the sound of the hand is strong between 50 and 70 cm and above 95 dB).
No wiring required, battery operated for safety even if it falls over.
