Car Helicopter Crash Collision Sensor Impact Switch Module for Arduino with Cable Key benefits Detects sudden impacts and collisions to protect and monitor small models and prototypes. Simple connection via included cable lets you add impact sensing to Arduino and other microcontroller projects quickly. Compact and lightweight so it fits inside RC cars, helicopters, drones, and mobile robots without affecting balance or performance. Provides a clear digital signal on impact so your controller can trigger logging, alerts, motor cutoffs, or recovery routines. What it does Acts as an impact switch that changes state when subjected to a collision or shock. Outputs a clean digital signal suitable for reading by Arduino digital inputs or similar microcontroller pins. Designed for model vehicles and robotic applications where rapid detection of a crash or bump is required. Compatibility and integration Intended for use with Arduino and most microcontroller platforms that accept a digital input. Includes a readymade cable for fast wiring and testing. Mounting and wiring require only basic electronics knowledge. Small footprint works well in tight spaces typical of RC models and compact robots. Key attributes Function: impact detection via mechanical/electrical switch module with digital output. Compatibility: Arduino and other common microcontroller boards using digital inputs. Size: compact form factor suitable for small models and robot chassis. Material and build: durable module and cable designed for installation inside moving models. Performance: dependable switching behavior on shock or collision for timely response by the controller. Practical applications RC car crash detection: automatically cut power to motors or log the event when a collision occurs. RC helicopter or drone protection: detect hard landings or impacts and trigger telemetry or safemode procedures. Mobile robot collision sensing: stop the robot, reverse, or navigate away after detecting a bump to prevent further damage. What you get Impact switch module with cable for immediate connection to Arduino and other controllers. A compact, easytoinstall component for adding crash and collision sensing to your models and prototypes. Notes for use Mount the module securely to the model structure to ensure accurate detection. Debounce or simple software filtering on the microcontroller can help avoid false triggers from vibration.
