Miniature Ultrasonic Distance Ranging Obstacle Avoidance Sensor (3m)

SKU: SEN0591

This 3m ultrasonic obstacle avoidance sensor is designed for robot automation control. It solves common market issues (large blind zones, wide angles, long response, poor adaptability). Key advantages: small blind zones, narrow angles, short response, same-frequency interference filtering, compact size, flexible installation, dust/waterproof, long lifespan. With innovative tech, it filters foreign ultrasound for stable data, meeting complex robot needs. It has RS485 output, compatible with Arduino’s TTL-to-RS485 board (DFR0259).
