Ultrasonic Sensor jarak Module HY-SRF05 untuk Arduino

Ultrasonic Sensor Module HY-SRF05, lebih presisi dari HC-SR04.



Product description:

Ultrasonic sensors overcome many of the weaknesses of IR sensors - they provide distance measurement regardless of color and lighting of obstacles.

They also provide lower minimum distances and wider angles of detection to gaurantee that obstacles are not missed by a narrow sensor beam.

This particular model is an upgrade from the lower precision HCSR-O4. This has 5 pins and can be used in 1-pin trigger/echo or 2-pin.



Measurement Procedure & Formula:

Send a 10 uS wide pulse to the sensor on the Trigger Pin. The sensor will automatically send out a 40 kHz wave.

Begin monitoring the output from the Echo Pin and

When the Echo Pin goes high, begin a timer.

When the Echo Pin goes low, record the elapsed time from the timer and use the following conversion formula:

Distance (in cm) = (elapsed time * sound velocity (340 m/s)) / 100 / 2

Note: we divide distance by 2 because the sensor returns the round trip time, which doubles the distance measurement.
