801S Vibration Sensor Module

This 801S module changes its resistance level once vibration is detected. It can turn into a switch if the vibration is high. According to the datasheet, it is gold-plated and can withstand 60 million shocks. This module is connected in a voltage divider which can be measured through its digital pinout. It’s a high sensitivity 801S Vibration Sensor module, which has one digital output pin(D0), When it detects some vibration up to a certain threshold, it can output High or Low level.

Comparing with other vibration or shock sensor, this 801S type has the following listed features:

1. This Vibration sensor is based on the Hi high precision vibration sensor 801S
2. it has 1 digital output
3. The sensitivity of TTL output can be adjusted by the on-board potentiometer

The 801S shock and vibration sensor, by itself, changes its resistance when subjected to vibrations. The resistance changes are so extreme that the 801S is like a switch. The datasheet claims that this gold plated device can withstand 60 million shocks. As with most resistance-varying devices, the 801S is connected in a voltage divider circuit to get a voltage output.
