Description
This ultrasonic module, equipped with the CS100A chip , is of high performance and low cost and boasts a wide voltage range from 3.3V to 5V.
It can measure distance from 4cm to 300 cm with high accuracy and stability so as to be well applied in distance measurements, robots, anti-theft devices and others.
Working Principle：
(1)Use trig Port to trigger 10us high level signals;
(2)Automatically send eight square waves of 40khz out and detect if there are signals sent back.
(3)If there are signals back, output a high level via echo.
Then the time lasting for high level is the time gap between the transmission and reception of the signals.
Measured distance(L) =(high level time* the speed of time(340M/S))/2.
