1. 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 a piezoelectric ceramic vibrates, it creates an electric charge. Using this principle, a vibrator consisting of two piezoelectric ceramics or one piezoelectric ceramic and a metal plate is applied.
2. Product introduction
Voltage: 5 v
Output signal LED indication.
TTL level output.
TTL output effective signal for high level. Output control current up to 1A can be external high-power LED lights.
Analog signal output, according to the vibration intensity of the output voltage is higher
Vibration amplitude sensitivity can be adjusted by potentiometer. (low left sensitivity, high right sensitivity)
Sensitivity can be adjusted to respond to blowing with the mouth... Sensitivity is very high!!!! You can also set it to tap with your hand.
Dimensions: 20.5X20.5 (in mm)
