Vibration sensor module alarm Motion sensor module vibration switch SW-420 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 adjust using an onboard potentiometer. When this no vibration, this module output logic LOW the signal indicates LED light, and vice versa.
The output can be directly connected to the microcontroller, which to detect high and low level, so as to detect whether the environment exists vibration, play a role in the alarm. It is useful for a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm.
- Do not reverse the power directions, otherwise, it is possible to burn the chip
- Signal LED light is output Low, signal LED OFF output is High
- The output level close to the input voltage.
- Using SW-420 normally closed type vibration sensor
- Comparator output, clean signal, good waveform, strong driving ability, >15mA
- Using a wide voltage LM393 comparator
- With bolt holes for easy installation
