Proximity, Distance & Collision

About

Proximity, distance, and collision detection sensors give your projects the ability to perceive and react to the physical world — detecting obstacles, measuring distances, and triggering responses without physical contact. From ultrasonic range finders to Hall effect proximity sensors, our range covers the essential non-contact sensing technologies for robotics, automation, and IoT applications. Our Proximity, Distance & Collision collection includes: Ultrasonic Distance Sensors — US-100 ultrasonic range finder modules with dual-mode operation (UART serial or trigger/echo pulse); measures distances from 2cm to 4.5m with ±1cm accuracy; ideal for obstacle avoidance, liquid level sensing, and parking assist systems Hall Effect Proximity Sensors — linear and analog Hall effect sensor modules for contactless magnetic proximity detection; detects the presence and polarity of magnetic fields for position sensing, end-stop detection, and RPM counting in motors and encoders IR Obstacle Avoidance Modules — infrared proximity sensors for short-range obstacle detection in line-following robots, conveyor systems, and automated guided vehicles All modules are compatible with 3.3V and 5V microcontroller logic levels and feature standard 2.54mm pin headers for direct connection to Arduino, Raspberry Pi, ESP32, and STM32 development boards.
