2pcs Ultrasonic Module Distance Sensor with 2pcs Mounting Bracket for Raspberry Pi Arduino Uno R3 Mega 2560 Nano Smart Robotics Projects

Description

• Ultrasonic Sensor Distance Module:using IO trigger for at least 10us high level signal.
• The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
• 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.
• 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.
• 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.

HC-SR04 is great for all kinds of projects that need distance measurements, avoiding obstacles as examples.

HC-SR04 provides a 2cm-450cm non-contact measurement function, the ranging accuracy can reach 2mm.
