Welcome to our shop! This Vibration Switch Sensor Module is designed to detect and generate vibrations using a piezoelectric ceramic sheet. When the ceramic piece vibrates, it generates an electrical signal. This module can be used in various interactive applications related to vibration, such as electronic drums. To use the module, connect the analog voltage ceramic vibration sensor to the controller's analog terminal A0. The output value can be observed through the serial port, allowing for vibration-related interaction work. The sensitivity of the vibration amplitude can be adjusted using the potentiometer. Higher vibration intensity results in a higher output voltage. This product has high sensitivity and can be adjusted to respond to a mouth blow or a tap with a hand. The sensitivity can be adjusted by turning the potentiometer clockwise (increased sensitivity) or counterclockwise (decreased sensitivity). The module also has a TTL level output with an LED indication. The module operates at a working voltage of 5.0V (DC) and has a working temperature range of -10°C to +70°C. Its compact size of approximately 20 x 20mm makes it easy to integrate into your projects. Please note that this module weighs approximately 4.5g. 100% Satisfaction: Our customers are our top priority.
