Description

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:

This Vibration sensor is based on the Hi high precision vibration sensor 801S
it has 1 digital output
The sensitivity of TTL output can be adjusted by the on-board potentiometer, you can also read the digital output with any ADC to get the vibration condition.

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.
