Generic MSG3M Normally Open Vibration Sensor Module

By Brand : Generic

Avg Customer Reviews :

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. Uses: For a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm. This module when compared with normally open pneumatic shock sensor module, shock triggered much longer can drive relay module. Module features: The use of the company's production of SW-420 normally, closed type vibration sensors. Comparator 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 comparator. 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 line, the green led is not lit. The output can be directly connected to the microcontroller, by single-chip computer to detect high or low level, to detect whether there is vibration, alarm function.
