Description

The 801S module utilizes a specialized vibration-sensitive element whose resistance changes dramatically upon mechanical shock or vibration. This change is processed by the onboard LM393 voltage comparator, which converts the analog signal into a clean digital output. When vibration exceeds the user-set threshold, the output pin switches state, providing a clear trigger signal.

Designed for reliability in embedded projects, the module’s simple digital interface makes it ideal for impact detection, anti-tamper alarms, and activity monitoring in DIY electronics and prototyping environments. Its robust construction is intended for repeated use.

Key Features

  • Digital Output Interface: Clean TTL/CMOS-compatible signal via LM393 comparator for easy integration with Arduino, Raspberry Pi, and other microcontrollers.
  • Adjustable Sensitivity: Onboard potentiometer allows precise calibration of the vibration detection threshold for different environments and mounting conditions.
  • Broad Voltage Compatibility: Operates from 3V to 5V DC, supporting both 3.3V and 5V logic families without requiring a level shifter.
  • Omni-Directional Sensing: Detects vibrations and shocks from any direction, simplifying placement and mounting.
  • Compact & Mountable Design: Small PCB footprint (35mm x 12mm) includes mounting holes for secure mechanical fixation in enclosures or on machinery.
  • Indicator LED: Provides visual confirmation of power and output signal status for debugging and operational feedback.

Applications

  • Impact and tamper detection for security enclosures, safes, or equipment cases.
  • Simple vibration monitoring in DIY projects, such as knock-activated switches or interactive installations.
  • Basic activity or usage detection for appliances, machinery, or fitness equipment.
  • Educational projects for demonstrating digital sensor interfacing and interrupt-based event detection.

Frequently Asked Questions

What is the output signal type of the 801S Vibration Sensor Module?

The module provides a digital output signal via the onboard LM393 comparator. When vibration exceeds the set threshold, the output pin switches to a logic low state; otherwise, it remains high. This clean digital signal is directly compatible with microcontroller GPIO pins for easy interrupt or polling-based reading.

How do I adjust the sensitivity of the sensor?

Sensitivity is adjusted using the blue potentiometer on the module. Turning it clockwise typically increases the sensitivity (lowers the detection threshold), making the sensor trigger more easily. Fine-tune it while testing with the expected vibration intensity to avoid false triggers or missed events.

What is the operating voltage range, and is it 3.3V compatible?

The module operates from 3V to 5V DC, making it fully compatible with both 3.3V and 5V microcontroller systems like ESP32, Arduino Uno, and Raspberry Pi. The digital output logic level will correspond to the supplied VCC voltage.

How should I mount the sensor for best performance?

For reliable detection, securely mount the PCB using its mounting holes to the surface you wish to monitor. A rigid connection ensures vibrations are transmitted effectively. The sensor is omni-directional, so orientation is not critical, but ensure the sensing element is not physically obstructed.
