Product Name: US-100 ultrasonic sensor / ultrasonic ranging for

     VCC, trig ( control side ), echo ( receiving end ), GND
        A control population of more than send a 10US high, you can wait to receive high output port . One has elapsed timer output can be opened , when this port goes low you can read the timer value , this when it 's time for this distance , only calculate the distance . this constant cycle of measurement , you can reach the value of the mobile measurement ~ ~
 module works:
( 1) The IO trigger ranging, high signal to at least 10us 's ;
( 2 ) the module automatically sends eight 40khz square wave and automatically detects whether a signal return ;
( 3 ) there is a signal to return through the IO outputs a high level, high duration is Ultrasonic time from launch to return . Test distance = ( time * High speed of sound (340M / S)) / 2;

    VCC, trig ( control side ), echo ( receiving end ), GND
       A control population of more than send a 10US high, you can wait to receive high output port . One has elapsed timer output can be opened , when this port goes low you can read the timer value , this when it 's time for this distance , only calculate the distance . this constant cycle of measurement , you can reach the value of the mobile measurement ~ ~
module works:
( 1) The IO trigger ranging, high signal to at least 10us 's ;
( 2 ) the module automatically sends eight 40khz square wave and automatically detects whether a signal return ;
( 3 ) there is a signal to return through the IO outputs a high level, high duration is Ultrasonic time from launch to return . Test distance = ( time * High speed of sound (340M / S)) / 2;
