The A21 module is an ultrasonic obstacle avoidance sensor designed based on robot automatic control application, focus on designing for problems on the current market ultrasonic sensor large blind spot, small measurement angle, long response time, poor installation adaptability and other problems, the A21 module has a series of advantages like small blind spot, large measurement angle, short response time, the same frequency filtering interference, high installation adaptability, dust and waterproof, long life and high reliability.

The intelligent acoustic processing technology independently developed by our company can identify and filter the interference acoustic wave, and output data more stable and reliable, making the A21 module reduce the probability of same frequency ultrasonic interference to a certain extent, and meet the users’ application needs for the complex environment in the filed of robot automatic control. A21 module, hereinafter referred to as “module”.
