HY-SRF05 SRF05 Ultrasonic Distance Sensor Module Pengganti Modul SR04

Arduino Compatible. 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 1002. Note: we divide distance by 2 because the sensor returns the round trip
