This is an ultrasonic obstacle avoidance sensor designed for robot automation applications. It addresses issues such as large blind zones, large measurement angles, long response times, and poor installation adaptability found in current ultrasonic sensor modules. It boasts advantages such as small blind zones, small measurement angles, short response times, filtering of co-frequency interference, small size, high installation adaptability, dust and water resistance, long lifespan, and high reliability. Combined with heterogeneous acoustic wave processing technology, it can identify and filter heterogeneous acoustic waves, resulting in more stable and reliable output data. This reduces the probability of ultrasonic co-frequency interference to a certain extent, meeting the application needs of users in complex environments in the field of robot automation control. IP67 protection rating: provides dustproof, waterproof, and oil-proof protection, suitable for humid and harsh measurement environments. High precision, more stable: 1mm resolution Room temperature measurement accuracy: 1+(S*0.3%)mm Small blind zone: blind zone as small as 2cm, detection range 2~300cm Large FOV detection angle: measurement angle 30~60° Color: Black Material: plastic Specification: UART Automatic Package Contents: 1*Ultrasonic Distance Sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
