HY-SRF05 Sensor Jarak Ultrasonic Sensor Measuring Module Arduino HC-SR

Deskripsi HY-SRF05 Ultrasonic Distance Sensor Measuring Module Arduino HC-SRF05 Description: This module performance is stable, precise measure distance.Can and foreign SRF05, SRF02 ultrasonic ranging module.Module with high precision, blind area (2 cm) very close, stable range is powerful according to the product to the market success! The main technical parameters: 1: using voltage: DC5V 2: the static current: less than 2 ma 3: high level output: 5 v 4: level output: 0 v 5: induction Angle: no greater than 15 degrees 6: detection range: 2 cm - 450 cm 7: high precision: up to 0.3 cm Working principle of the module: (1) the IO trigger range, high level signal for at least 10 us; (2) module automatically sent eight 40 KHZ square wave, automatically detect whether there is signal to return; (3) have returned signal, through the IO output high level, the duration of the high level is the time of ultrasonic wave from launch to return. The test distance = (high level of time * sound velocity (340 m/S)) / 2.
