Impact Collision Switch Sensor Module For Arduino

Impact Collision Switch Sensor Module For Arduino is an essential, straightforward digital sensor module that allows your microcontroller project to detect physical impacts or sudden contact. This robust module features a simple momentary contact switch (often a tilt, vibration, or metal ball switch) which registers a logical ‘LOW’ signal upon collision. Consequently, it offers an immediate and reliable signal for safety applications, obstacle avoidance, or interactive projects. Designed for easy integration with platforms like Arduino, Raspberry Pi, and other microcontrollers, this collision sensor uses minimal components while providing fast response times. Therefore, developers widely utilize this cost-effective module for adding a physical detection layer to small robotic and automation systems.

Key Features:

• Digital Output: Provides a clean, binary digital signal (HIGH or LOW) that microcontrollers can easily process.
• High Sensitivity: The contact switch detects even light physical impact or pressure, offering prompt feedback.
• Low Power Consumption: This module requires minimal operating current, making it ideal for battery-powered or portable robotics.
• Adjustable Sensitivity (Optional): Some variants include a potentiometer, however, the basic switch version provides fixed, high sensitivity collision detection.
• Standard Interface: The 3-pin interface (VCC, GND, DO) ensures quick and simple wiring to most development boards.

Technical Specifications:

• Operating Voltage (V_CC): 3.3 V to 5 V DC
• Output Type: Digital Switch Output
• Output Signal: HIGH (No Collision/Idle), LOW (Collision Detected/Contact)
• Output Current (I_out): ≤ 15 mA (Safe current for direct connection to microcontrollers)
• Switch Type: Momentary Contact Switch (Typically a tactile or ball switch)
• Module Dimensions: ≈ 32 mm x 14 mm (Varies by manufacturer)

Mechanical Specifications:

• Board Material: FR-4 PCB
• Mounting Holes: Typically one or two M3 mounting holes for easy installation onto chassis.
• Component Type: Low-profile through-hole components (resistors, LED, switch).
• Detection Mechanism: Physical deformation/contact closes an internal circuit.

Dimensions:

• Module Length: ≈ 3.2 cm
• Module Width: ≈ 1.4 cm
• Weight: ≈ 3 g (Extremely lightweight for mobile applications)
• PCB Thickness: 1.6 mm

Pinout and Wiring:

• VCC: Connect this pin to the 5V or 3.3V power supply of your microcontroller.
• GND: Connect the ground pin to the system ground (0 V).
• DO (Digital Output): Connect this pin directly to a digital input pin (GPIO) on your Arduino or other microcontroller.
• Wiring Note: The output is pulled HIGH internally or via an onboard resistor; the switch pulls the signal LOW upon impact.
