Piezoelectric shock tap sensor Vibration switch module for Arduino

Piezoelectric shock tap sensor Vibration switch module for Arduino

When a voltage is applied to a piezoelectric ceramic, mechanical deformation occurs as a function of voltage and frequency. On the other hand, when the piezoelectric ceramic is vibrated, an electric charge is generated. Using this principle, when a vibrator composed of two pieces of piezoelectric ceramics or one piece of piezoelectric ceramics and one metal piece is given.

Voltage: 5V

Output signal LED indication.

TTL level output.

The TTL output effective signal is high level. The output control current can reach 1A, and high-power LED lights can be connected.

Analog signal output, according to the greater the vibration intensity, the higher the output voltage

Vibration amplitude sensitivity can be adjusted by potentiometer. (Left turn sensitivity is low, right turn sensitivity is high)

Sensitivity can be adjusted to respond to blowing with the mouth.Sensitivity is very high.It can also be adjusted to be tapped by hand to have output.

Size: 20.5X20.5mm
