SRF-06 Ultrasonic Distance Range Sensor Finder Module For Arduino
Description:
- power supply :5V
- DC quiescent current : <2mA
- effective angle: <15°
- ranging distance : 2cm – 500 cm
- resolution : 0.3 cm
How to use:
How work:
(1) using IO trigger distance, the high signal to at least 10us;
(2) module automatically sends eight 40khz square wave, automatically detect whether a signal return;
(3) a signal back, through the IO output a high level, high duration is ultrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) / 2
10US a control population of more than a high-fat, you can wait for high output at the receiving port. One has to open the timer output can be,when the port goes low, the timer value can be read, this when the time for this distance, only calculate the distance that the constant cycle ofmeasurement, you can move up the value of the measured
