           2. Functions     (1)The module is stable performance,accurate distance measurement. It can be the same fast as the                     SRF05 and SRF02 module.   (2)Small volume ,easy to use.   (3) Low voltage, low power consumption   (4) High precision measurement   (5) Strong anti-interference   (6) The integrated enclosed waterproof with line is suitable for damp and bad measurement environment.   3.Basic working principle    (1)Use IO port TRIG to distance measurement .High level signal more  than 10us   (2)The module automatically sends a square wave of 8 number 40khz to detect if there is a signal to                       return automatically.   (3)If there is a signal to return, input a high level via IO port ECHO.The duration of the high level is the amount of time that the ultrasound go from launch to return(test distance=time of high level *speed of sound340m/s)/2   4.Operation method    The control port sends a  above 10us TTL and then waits for TTL output at the receiving port.set the timer once has output.The timer can be read when the receiving port becomes 0 that is time of distance measurement. Then can work out distance of measurement. With this cycle test constantly, you can achieve the value of your movable distance measurements.    5.Ultrasonic distance measurement  sequence diagram                     Packaging & Shipping   Package :       Standard export carton package Company Information               We are professional to undertake various tapes designs ,micro-controller development, circuit design and post production testing integration services of intelligent electronic products, mechanical and electrical control products.
