Beskrivelse
Avstandsmåler Ultrasonic Module HY-SRF05 Distance Measuring Transducer Sensor For eg. Arduino, NodeMCU, ESP, Raspberry PI osv
Module Working Principle:
- Pull the Trig pin to high level for more than 10us impulse, the module start ranging.
- The module automatically sends eight 40KHz square wave to detect whether a signal is returned.
- Finished ranging, If you find an object in front, Echo pin will be high level, and based on the different distance, it will take the different duration of high level.
- So we can calculated the distance easily.The distance=((Duration of high level)*(Sonic:340m/s))/2
