Description: The SW-420 sensor module produce logic states depending on vibration and external force applied on it. When there is no vibration this module gives logic LOW output and when it feels vibration the output goes to logic HIGH. The working voltage of this module is between 3.3v to 5v DC and has a potentiometer to set sensitivity. Operating Voltage : 3.3-5V Output: Digital low/high 0/1 Current : 15mA Using LM393 Comparator Size: Approx. 32x 14mm/ 1.26x 0.55inch Specification: Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, then alarm Package Includes: 1 Piece Vibration Tilt Sensor Module
