* Output signal: Electric frequency signal, high level 5V, low level 0V;
* Sensor angle: Not more than 15 degrees;
* Detection distance: 2cm-500cm (Actually up to 2.5m)
* High precision: Up to 0.3cm
How it works:
* Send 12us pulse to pin Trig, to start measurement
* The ultrasonic module will automatically send eight 40khz square waves, automatically detects whether there is a reflect signal
* When there is an reflect signal back, the Echo pin will output a high level, the duration of the high-level signal is the time (Techo) from ultrasonic launch to return.
* As a result, the Measured distance = (Techo * (Sound speed (340M/S))) / 2;
(Suggested measure period should >60ms to avoid the wrong echo signal)
