## Description

Parameters:HC-SR04 Ultrasonic Module details:Working Voltage: DC5V;Quiescent current: <2mA;Output signal: Electric frequency signal, high level 5V, low level 0V;Sensor angle: <15 degrees;Detection distance: 2cm-450cm/0.78-177.16 in;High precision: Up to 0.3cm/0.12 in;Input trigger signal: 10us TTL impulse;Echo signal: Output TTL PWL signalThere are 4 pins out of the module: VCC, Trig(control side), Echo(receiver), out (empty) GNDMounting Bracket:1. Thickness :2.8-3.1mm2. Inner diameter: 16mm3. Fixing Hole Diameter: 3.8mm4. Material: imported acrylic5. Application: Stationary ultrasonic sensor modules.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 pinwill be high level, and based on the different distance, it will take the different duration of high level.Then we can calculated the distance easily.The test distance = (Duration of high level * speed of sound (340M/S))/2If you have any question, please contact us via email to get support.Package Including5 * HC-SR04 Ultrasonic Module5 * Cartoon Mounting bracket20 * Acrylic Board Screws5 * Du-Pont Wire

## Features

- The mounting bracket is great fit for the HC-SR04, light weight for small servo, and it adds personality to your HC-SR04.
- HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. When trigged it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
- Ultrasonic Module: The detection zone: 0.78-177.16 in/ (2cm-450cm); High precision: up to 0.12 in/(0.3 cm); Effectual angle: less than 15°
- Power Supply: 5V DC. Quiescent current: less than 2mA.
- Package Including: 5 * HC-SR04 Ultrasonic Module + 5 * Mounting bracket + 2 * Acrylic Board + Screws.

### ⭐ 1.0 out of 5 stars







  
  
    Vary unreliable output
  

*by R***H on Reviewed in the United States 🇺🇸 on April 22, 2019*

Sometimes it gets stuck forever and needs to restart to read correctly. Not original sensor, the firmware has some major bug.
