801S Vibration Shock Sensor Module 3pin

Description

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 801s 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.

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

Features:

• Outputs a logic HIGH when module senses a vibration
• On-board LED indicator
• A gold alloy plating ensures a long service life of sensor (60,000,000 times)
• 3.3V and 5V logic compatible
• Micro-Shock detecting
• Digital output signal
