Introduction
SW-420 and LM393 Comparators are used to detect vibrations and the threshold can adjust using an onboard potentiometer. when there is no vibration, this module output logic LOW signs LED light and vice versa. If the module vibration is detected, the sensor provides Logic High. The SW-420 vibration switches momentarily disconnect, the output is pushed excessively, and the inexperienced mild no longer shine. The output may be directly connected to the microcontroller, which locates high and low stage, so as to detect whether the environment exists vibration, play a role in the alarm.
Features of SW-420 Vibration Sensor
- Using SW-420 normally closed-type vibration sensor
