2cm Blind Zone IP67 High Precision Ultrasonic Sensor

Features of the A22 module include millimeter resolution, 2cm to 300cm range, reflective construction and severaloutput types: UART output ,UART controlled output,RS485 output,IIC output.

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 A22 module reduce the probability of co-frequency ultrasonic interference to a certain degree, and meet the users’ application needs for the complex environment in the filed of robot automatic control.

• Wide voltage power supply, working voltage:3.3～12V (Maximum support 24V);

• 2cm standard blind area(product blind area can up to 1.5cm minimum);

• The farthest range can be set, a total 4-level range of 50cm、150cm、250cm and 350cm can be set through instructions;

• A variety of output modes are available,UART auto / controlled, PWM controlled, switch volume TTL level, RS485,IIC,etc. Although the output mode is different, the function is exactly the same;

• The default baud rate is 115,200, Supports modification to 4800，9600，14400，19200，38400, 57600, 76800;

• Ms-level response time, data output time can up to 13ms fastest

• Single angle measurement range is wider; single angle can support 4-level settings of 30°、40°、50°、60° to apply to different application scenarios;

• Built-in noise reduction function which can support 5-grade noise reduction level setting, suitable for battery power supply,short and long distance USB power supply, switch power supply and large noise power supply;

•Intelligent acoustic wave processing technology, built-in intelligent algorithm to filters interference sound waves; When the co-frequency interference is present in the detection environment, the “FFFE” data is output to make a prompt, which can identify the interference sound waves and automatically perform filtering, the correct rate is increased by 80% in the co-frequency interference environment;

• Waterproof structure, waterproof grade IP67

• Ultra-wide temperature design, Working temperature -25°C to +65°C
