801S Vibration Shock Sensor Module Sensor Module CR2032 battery backup with twoThe 3 pin 801S Vibration Sensor Module is based on 801S Vibration Sensor which works on the principle that when the movement or vibration occurs the resistance changes and even working as switch if high vibrations is detected. It has a gold plated measuring sensor so it is reliable and will work for a long time. The sensitivity of this can be controlled by an onboard potentiometer and LM393 Comparator IC. This is very useful in detecting Collisions,
