Vibration Sensor Module Normally Opened Type Vibration switch LM393 for Arduino
The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED light,And vice versa.
Module features: the use of the company's production of SW-420 normally closed type vibration sensors. compactor output signal clean wave well, driving ability, 15mA rated voltage and 3.3V-5V output: digital switching output (0 and 1) a bolt-hole for easy installation small Board PCB dimensions: 3.2cm x 1.4cm using wide LM393 voltage compactor
Module description: The product when it is not shock, vibrate switch is closed on-State, output output low level, the green indicator light is on; When vibration, vibration switches disconnected moments, output output line, the Green led is not lit; the output can be directly connected to the micro controller, by single-chip computer to detect high or low level, to detect whether there is vibration, alarm function
Uses: For a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm.
