5Pin HY-SRF05 SRF05 Ultrasonic Ranging Module Ultrasonic Sensor Replace SR04 Module

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 2mA 3: high level output: 5V 4: level output: 0V 5: induction Angle: no greater than 15 degrees 6: detection range: 2 cm - 450 cm 7: high precision: up to 0.3 cm

This product use: a mouth sends a high level of more than ten us, you can receive the mouth for high level output. To be able to open the timer timing, an output when the mouth into a low electricity at ordinary times you can read the value of the timer is here for the distance of time, can calculate the distance. So constantly cycle test, you can reach your mobile measuring the value of the ~ ~

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;
