Module Performance:

* Voltage: DC5V;

* Static current: Less than 2mA;

* 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)
