Vibration Sensor Module (801S)

Regular price LE 145.00



The 801S Vibration Sensor Module is a sensitive micro shock detecting sensor that operates by changing its resistance when a shock or vibration is detected.

The sensor operates in any orientation and is extremely sensitive to any type of movement such as a light tap or vibration.  Unlike many sensors that use a mechanical switching element, this sensor uses resistive element that changes resistance with motion.

The module output is normally LOW and outputs a series of random HIGH pulses when a vibration or shock is detected.  The on-board LED is normally ON and goes OFF momentarily or appears to flicker when a shock is detected.  It can take up to 2 seconds for the output to return to a steady LOW after the shock / vibration is removed

There are two variants we have seen on this module with different resistor values.  The current draw is either about 2mA or about 10mA @ 5V.  Most of that is due to the on-board LED.

The module includes an LM393 comparator with a potentiometer to allow adjustment of basic sensitivity level.  Turning the potentiometer CCW increases sensitivity.
