2 Pcs Piezoelectric Vibration Tapping Sensor Module AD DO Output Adjustable Sensitivity Vibration Switch Module

Feature: 1. Working Principle: An analog vibration sensor based on a piezoelectric ceramic sheet is an inverse conversion process that uses piezoelectric ceramics to generate vibration. When the piezoelectric ceramic piece vibrates, an electrical signal is generated. 2. Versatile Use: Special sensor expansion boards are used in combination, and analog ports can be weakly perceived. Vibrating electrical signals enable interactive work related to vibration, such as electronic drum interactions. 3. ADO Output: The analog voltage ceramic vibration sensor can connect to controller analog port A0 according to the program. When the vibration level is different, observing output value of serial port, can achieve interactive work related to vibration. According to the vibration strength, the higher the output voltage, the higher the vibration amplitude. 4. Adjustable Sensitivity: Sensitivity can be adjusted by the potentiometer (low sensitivity for left turns, high sensitivity for right turns). Can be adjusted to have a response when blowing with the mouth or output when tapping with the hand. 5. DO Output: TTL level output, output signal LED indication. The TTL output valid signal is high level, and the output control current can achieve 1A for external high power LED lights.
