801S Vibration Sensor
The 801S Vibration Sensor Module is designed to detect vibration, knocks, and mechanical shocks with high sensitivity. It features an LM393 voltage comparator and an adjustable potentiometer for sensitivity calibration.
This module provides a digital output that changes state whenever the detected vibration exceeds the preset threshold, making it suitable for security systems, machine monitoring, smart home automation, robotics, and embedded electronics.
Its compact size and simple 3-pin interface make it easy to integrate with Arduino and other microcontrollers.
