Miniature Ultrasonic Distance Ranging Obstacle Avoidance Sensor (3m, RS485, IP67)

The RS485 ultrasonic obstacle avoidance distance ranging sensor boasts a remarkable measurement range extending up to 3 meters, ensuring superior performance in various robotics and automation tasks. It features a small blind zone with a measurement accuracy of 1 + (S * 0.3%) cm, allowing for precise obstacle detection even in cluttered environments.

Its narrow measurement angles, spanning 30 to 60 degrees, provide focused detection capabilities, while the short response times ranging from 15 to 750 milliseconds enable real-time data processing. The sensor's compact design and high installation adaptability make it an excellent choice for projects requiring space efficiency and ease of integration.

With IP67-rated dust and waterproof protection, the sensor is built to withstand harsh environmental conditions, ensuring a long lifespan and high reliability. Its innovative ultrasound processing technology effectively filters out foreign ultrasound, reducing the chances of same-frequency interference and delivering stable and dependable data output.

The RS485 output interface facilitates seamless data transmission and can be easily used in conjunction with an Arduino TTL to RS485 expansion board. This makes it an invaluable component for various applications including robot obstacle avoidance, automatic control, parking management systems, security gate detection, access control systems, and object proximity and presence detection.
