Keyestudio RJ11 EASY plug Collision Crash Sensor Module for Arduino STEAM

The Keyestudio RJ11 EASY plug Collision Crash Sensor Module is a highly sensitive snap-action switch designed for students, educators and hobbyists exploring STEAM. This digital on-off input module detects physical contact with minimal force, making it an essential component for elementary electronics and robotics projects.

Sensitive snap-action switch

This collision sensor operates as a digital on-off input module that is actuated by very little physical force. It serves as an essential component for elementary electronics, helping beginners understand physical input mechanisms.

Versatile programming applications

With simple programming, this module can be used to control lights, sound devices, LCD display key functions, and 3D printer position feedback. It offers a practical way to introduce real-world feedback loops to classroom projects.

EASY plug RJ11 connection

The sensor is equipped with an RJ11 6P6C interface designed for seamless compatibility with the Keyestudio EASY plug Control Board. Please note that it is incompatible with other brands of RJ11 control boards due to differing internal line sequences.

Onboard LED and mounting

An onboard status indicator LED provides immediate visual feedback during operation. The module also includes a convenient M3 mounting hole, making it simple to secure the sensor to your robot chassis or custom project enclosure.

Simple digital output logic

The module outputs a LOW level signal when a collision occurs and a HIGH level signal when there is no contact. This straightforward digital logic simplifies coding and troubleshooting for young makers.
