Piezo sheet Percussion Shock Tap Vibration sensor Switch module for Arduino
1. Brief introduction of components
When the voltage acts on the piezoelectric ceramic, it will produce mechanical deformation with the change of voltage and frequency. On the other hand, when the piezoelectric ceramics are vibrated, an electric charge is generated. Based on this principle, a vibrator composed of two pieces of piezoelectric ceramics or one piece of piezoelectric ceramics and one piece of metal is designed
2. Product introduction
Voltage: 5V
The output signal is indicated by LED.
TTL level output
TTL output valid signal is high level. The output control current can reach 1a. It can be connected with high power LED lamp.
Analog signal output, according to the vibration intensity, the greater the output voltage
The sensitivity of vibration amplitude can be adjusted by potentiometer? Left turn sensitivity low, right turn sensitivity high)
The sensitivity can be adjusted to respond when blowing with the mouth... The sensitivity is very high!!!! It can also be adjusted to manual tapping to get output.
Size: 20.5x20.5 (mm)
