Feature: 1. NOT AFFECTED BY ENVIRONMENT: Ultrasonic distance sensor is suitable for various application environments, which is not affected by color, transparency and material (metal, non metal) of detected objects 2. STABLE OUTPUT: The distance sensor can minimize power consumption according to practical application, has strong stability, built in intelligent algorithm, stable circuit design, bring stable and reliable data output 3. WATERPROOF PROTECTION: Range detector has IP67 protection level, has a certain dustproof, waterproof and oilproof grades, suitable for humid and harsh environment 4. WIDE APPLICATIONS: The sensor is suitable for all scene object proximity detection, parking management system, robot obstacle avoidance, automatic control, etc. 5. SUPPORT POWER NOISE REDUCTION LEVEL SETTING: The sensor is suitable for battery power supply, short or long distance USB power supply, switching power supply, and large noise power supply 6. UPGRADE DESIGN: A22 module is a kind of ultrasonic obstacle avoidance sensor designed based on robot automatic control application, which focuses on the design for ultrasonic sensor module in the current market, such as large blind area, large measurement angle, long response time, poor installation and adaptation 7. VARIOUS ADVANTAGES: A22 module sensor has a series of advantages, such as small blind area, small measurement angle, short response time, filtering the same frequency interference, small size, high installation adaptability, dustproof and waterproof, long life and high reliability 8. FOREIGN ACOUSTIC PROCESSING TECHNOLOGY: Large FOV detection angle supports 30~60°. When the detection environment has the same frequency interference, the sensor will output FFFE data to indicate the existence of the same frequency interference Specification: Item Type: Ultrasonic Distance Sensor Measurement Accuracy: ±(1+Sx0.3%) Operating Voltage: DC3.3V-12V Blind Area Distance: < Approx. 2cm / 0.8in Output Response Time: 300-1500ms Output Mode: IIC output Temperature Compensation: Yes Planar Range: Approx. 2 ~ 200cm / 0.8 ~ 78.7in Application: Robot obstacle avoidance, intelligent garbage can detection, parking space detection, intelligent home, etc..
