HY-SRF05 SRF05 Ultrasonic Sensor Ultrasonic Ranging Module

Technical Parameters:
1: Use voltage: DC5V
2: Quiescent current: less than 2mA
3: Level output: 5V high
4: Level output: bottom 0V
5: Induction angle: no more than 15 degrees
6: Detection distance: 2cm-450cm
7: High precision: up to 0.3cm
The use of this product: a control port sends a high level of 10US or more, you can wait for the high level output at the receiving port. When there is an output, you can start the timer, when the port becomes low, you can read the timing. The value of the device, at this time is the time of the distance measurement, in order to calculate the distance. Such continuous cycle measurement, you can reach the value of your mobile measurement.

Working principle of the module:
(1) Using IO trigger ranging to give a high level signal of at least 10us;
(2) The module automatically sends eight 40khz square waves to automatically detect whether there is a signal return;
(3) There is a signal return, a high level is output through IO, and the high level continues Ultrasonic time from launch to return. Test distance = (high time * sound speed (340M / S)) / 2
