Ultrasonic ranger
The iTriangle - Ultrasonic ranger is a non-contact distance measurement module that works at 40 KHz. When a pulse trigger signal with more than 10 uS is provided through the signal pin, the module will issue 8 cycles of 40 kHz and detect the echo. The pulse width of the echo signal is proportional to the measured distance according to the formula: distance = echo signal high time * Sound speed (340 m/s)/2. The Ultrasonic Ranger's TRIG and ECHO signal share 1 SIG pin.
Do not hot plug the ultrasonic ranger, otherwise the sensor will be damaged. The measured area must be no less than 0.5 square meters and smooth.
