5V Piezoelectric Film Vibration Sensor Switch Module TTL Level Output ForArduino

Description

1. Introduction to components
When the voltage acts on the piezoelectric ceramic, it will be with the voltage and frequency changes in mechanical deformation. On the other hand, when vibrating the piezoelectric ceramic, a charge is generated. The use of this principle, when given by two piezoelectric ceramics or a piece of piezoelectric ceramic and a metal plate composed of vibrators.
2. Product brief
Voltage: 5V
Output signal  indication.
TTL level output.
TTL output valid signal is high. Output control current up to 1A can be an external high power lights and so on.
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 low right turn high sensitivity)
Sensitivity can be adjusted with a mouth blowing response. The The Sensitivity is very high! The The The Can also be transferred to the hand percussion only output.
Size: 20.5X20.5 (in millimeters)
Weight: 4.25g
