1. The performance of this module is stabile, measure distance of it is accurate. When it comes to foreign SRF05, SRF02 and other ultrasonic ranging modules, it is precision. The module is of high precision, the blind area (2cm) is very near, the stable ranging is powerful base with which the product go into the market successfully!2. Main technical parameters:1) using voltage: DC5V2) quiescent current: less than 2mA3) level output: high 5V4) level output: low 0V5) induction angle: no more than 15 degrees6) detection distance: 2cm-450cm7) high accuracy: up to 1mm3. Connection mode:VCC, trig (control end), echo (receiving end), GND4. Using method:4 using method:A control port send a high level more than 10US, at this time you can be waiting for the high level output at the receiving port. Once there is a output, the timer can be opened, when the port become low level you can read the timer value. This point is the time of this ranging, you can calculate the distance. So by cycle detection, you can get your mobile measurement value ~ ~5 Module working principle:(1) use IO trigger ranging is used and give a high signal of at least 10us;(2) the module automatically sends 8 40KHz Fang Bo and automatically detect whether a signal is returned;(3) If a signal is returned, a high level is output via a IO, the last time of the high level the time from transmitting to returning. The test distance = (high level time * sound velocity (340M/S)) /2;
