801S Vibration Shock Sensor Module – Digital Output for Microcontrollers
801S Vibration Shock Sensor Module – Digital Output with Adjustable Sensitivity
The 801S Vibration Shock Sensor Module is a compact digital sensor that detects vibrations, shocks, and tilts. It uses an LM393 comparator and a spring-based vibration switch to provide a clean digital HIGH/LOW signal when vibration exceeds the adjustable threshold. This module is ideal for alarm systems, impact detection, and interactive DIY projects with microcontrollers like Arduino.

Compatibility
This sensor module works with any microcontroller supporting 3.3V or 5V logic, including Arduino Uno, Nano, Mega, ESP32, and Raspberry Pi Pico. It connects to a digital GPIO pin and requires no additional hardware for basic operation. The onboard potentiometer allows fine-tuning for different vibration levels.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, and DO to a digital input pin on your microcontroller. The module outputs a digital HIGH normally and pulls the signal line LOW when vibrations exceed the set threshold. No external pull-up resistors are required for stable operation.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the 801S module works directly with the Arduino Uno. Connect the DO pin to any digital input and use digitalRead() to detect vibrations.
How sensitive is this vibration sensor?
Sensitivity is adjustable via the onboard potentiometer. Turn clockwise to increase sensitivity for faint vibrations or counterclockwise to require stronger shocks to trigger.
Does this sensor detect continuous vibration or just shocks?
It detects both shocks and continuous vibration. The spring-based switch closes upon movement, and the comparator holds the output LOW as long as vibration persists above the threshold.
