This Collision Detection Switch Module is a compact and reliable mechanical contact sensor designed for basic obstacle detection in DIY robot cars, automated vehicles, and microcontroller-based systems. It features a front-end mechanical switch that detects collisions and provides a clear digital output for your microcontroller.
When the switch is pressed (collision detected), the module outputs a LOW signal, and an indicator LED lights up. When no collision occurs, the output is HIGH, and the LED remains off.
Thanks to its compact size and M3 mounting holes, this module can be easily secured to a robot chassis or platform. It works with a wide voltage range from 3V to 12V, making it compatible with most development boards like Arduino, ESP32, Raspberry Pi, and more.
⚠️ Note: Dupont wires not included.
