SRF05 Ultrasonic Module Features SRF05 is an ultrasonic transmitter and receiver module used to measure distance. The sensor operation is very simple. You only need to measure the return time of ultrasonic waves in order to measure the distance. Then you should divide measured time by 2 and multiply by the sound speed. The sensor measuring range is about 2 to 400 cm. You can download the datasheet of this module here. [wpdm_package id='17336'] SRF05 Ultrasonic Module Pinout This sensor has 3 pi...
