Description

This sensor functions as a simple, yet highly effective, mechanical switch designed to detect physical collisions or sudden impacts. Its internal mechanism is calibrated for high sensitivity and stability, providing a definitive digital HIGH/LOW signal when a force threshold is exceeded. This makes it ideal for applications where a basic, reliable trigger is needed without the complexity and cost of a full inertial measurement unit (IMU).

The module is built around the Grove system, featuring a 4-pin connector that carries VCC, GND, and the digital signal output. This design ensures quick integration into prototyping platforms and eliminates common wiring errors. Its compact form factor and mounting hole allow for secure installation in robotics, enclosures, or interactive projects where impact monitoring is required.

Key Features

  • High-Sensitivity Mechanical Switch: Engineered for reliable detection of low-force collisions and impacts.
  • Omnidirectional Trigger Design: Detects impacts from any angle, providing comprehensive event monitoring.
  • 3.3V/5V Logic Compatible: Interfaces seamlessly with a wide range of microcontrollers and single-board computers.
  • Plug-and-Play Grove Interface: Leverages the standardized Grove connector system for rapid prototyping and development.
  • Debounced Digital Signal Output: Delivers a clean, stable signal to the microcontroller, minimizing false triggers.
  • Compact and Lightweight Construction: Small footprint (90mm x 130mm) and low weight (8g) for easy integration into space-constrained designs.
  • RoHS/WEEE Lead-Free Compliance: Manufactured with environmentally conscious materials and processes.

Applications

  • Robotics Bumper and Collision Detection: Installed on robot chassis to trigger evasion routines or stop motors upon impact.
  • Interactive Installation and Game Controllers: Used as a physical input button activated by striking or tapping.
  • Simple Security and Tamper Detection: Monitors enclosures or doors for unauthorized opening or forceful entry.
  • Prototype Impact Logging: Integrated into devices to record and count the number of physical shock events.
  • Educational Kits for Sensor Fundamentals: Demonstrates basic digital input and event-driven programming in electronics courses.

Frequently Asked Questions

What is the output signal type of this collision sensor?

The module provides a simple digital output signal. When a collision is detected, the output pin switches state (typically from HIGH to LOW, or vice-versa, depending on configuration), providing a clean signal directly readable by a microcontroller's digital input pin.

Can I use this sensor with both 3.3V and 5V Arduino boards?

Yes, the module is designed to operate across a wide voltage range of 3.3V to 5V DC. You can power it and interface it directly with 3.3V logic boards like the Raspberry Pi or ESP32, as well as 5V boards like the Arduino Uno, without requiring a logic level converter.

How do I connect this module to my microcontroller?

Connection is simplified via the Grove 4-pin connector. Simply plug a Grove cable from the module into a Grove port on a compatible base shield (like the Grove Shield for Arduino) or a Grove-to-female Jumper cable adapter. The cable carries VCC, GND, and the digital signal output to your board.

Is the sensor sensitive to light touches or only hard impacts?

It is a high-sensitivity mechanical switch designed to detect distinct collisions or impacts. It is not typically triggered by light vibrations or touches, but by a definitive force that actuates the internal switch mechanism, making it suitable for detecting bumps, taps, or strikes.
