Specification Brand : Walfront BulletPoint1 : Inverse Transformation: An analog vibration sensor based on a piezoelectric ceramic sheet is an inverse transformation process that uses piezoelectric ceramics to generate vibration. When the piezoelectric ceramic piece vibrates, an electrical signal is g BulletPoint2 : Application: 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. BulletPoint3 : ADO Output: The analog voltage ceramic vibration sensor is connected to the controller analog terminal A0 according to the program. When the vibration degree is different, observing the output value of the serial port can realize the vibration-related int BulletPoint4 : Vibration Intension: According to the greater the vibration intension, the higher the output voltage, the sensitivity of the vibration amplitude can be adjusted by the potentiometer. BulletPoint5 : High Sensitivity: This product has high sensitivity and can be adjusted to respond with a mouth blow or an output with a hand tap (Low turn sensitivity is low, right turn sensitivity is high).

Test Method and Wiring: G (GND):: Power ground V (VCC): Operating voltage 5V (DC) ADO: Analog signal output According to the vibration intension, the higher the output voltage, the higher the vibration amplitude sensitivity can be adjusted by the potentiometer (the left turn sensitivity is low, the right turn sensitivity is high). The high sensitivity output can be adjusted to respond with a mouth blow or a tap with a hand. DO: TTL level output. Output signal LED indication. TTL output valid signal is high level, output control power
