Module consisting of ultrasonic transmitter, receiver and control circuit. Basic working principle: 1. Use the IO mouth Trig trigger distance, at least 10 US signals with high level; 2. The module automatically sends eight 40 kHz square waves and automatically detects whether a signal is returned. 3. I returned the signal, through the IO mouth, Echo output a high level, the duration of the high level is the time of the ultrasonic wave from start to return. 4. Distance = test (high level time sound speed (340 m\/s)) \/ 2; Operating voltage: DC 5 V. Operating current: less than 2 mA. Operating frequency: 40 Hz. Maximum range: 450 cm. Minimum range: 2cm. Measuring point: 15 degrees. Input trigger signal: 10US TTL pulse Echo signal output: output of the TTL level signal, proportional to the range.
