Description

Features:

1.HC-SR04 Ultrasonic Sensor Distance Module:using IO trigger for at least 10us high level signal.

2.The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.

3.If the signal back,through high level,time of high output IO duration is the time from sending ultrasonic to returning.Test distance = (high level time velocity of sound (340M/S)/2.

4.Power Supply:5V DC;Quiescent Current:<2mA;Effectual Angle:<15°;Ranging Distance:2cm~450cm;Resolution:0.3 cm,Module precision:blind spots (2cm)-SUPER CLOSE.

5.The module performance is stable,measure distance accurately.SRF05,SRF02 ultrasonic ranging module comparable.This module is compatible with GH-311 anti-theft module.

The Xiao R Geek HC-SR04 Ultrasonic Distance Measuring Sensor Module includes an ultrasonic transmitter,receiver and circuits.It has 4 pins:VCC,TRIG,ECHO and GND.The anti-reverse pin header onside makes it easy to connect and apply.With 2pcs Mounting Bracket for Arduino Uno R3 Mega 2560 Nano Raspberry Pi 3 Smart Robotics Projects



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

Package includes:
2*HC-SR04 Ultrasonic Distance Sensor
2*HC-SR04 Mounting Bracket

Male to Female jump wires 8pin
