 ## Description
 
-**SONIC** It is an ultrasonic distance measuring sensor unit, which adopts the design of receiving and transmitting separately. The ultrasonic probe has a sound frequency of 40KHz, a direction angle of 80 ± 15 ° and an accuracy of 1cm. The internal part is calculated by rcwl-9600 ultrasonic distance measuring chip, and the measurement results can be directly obtained through IIC interface (0x57). The effective distance is 20-1500mm.
