Product Description

HC-SR04 Distance Ultrasonic Sensor Module for steam eduacation
Module description:
This module is used to measure the distance.By sending and receiving ultrasonic waves, it measures the time required for the sound to rebound from the object and return to the sensor.Using the time difference and sound propagation speed, it calculates the distance between the module and the obstacles in front.
Parameters:
Working voltage: 3.3V~5V
Minimum measurement distance measurement: 2cm
Maximum measurement distance measurement: 350cm
Type: Echo is the input digital signal, trig is the output digital signal.
Interface mode: Ph2.0-4p
Module size: 43 x 25mm
Module weight: 86g
Pin definition:
Echo: recive input
Trig: transmit output
-: GND
+: VCC
Working principle:
input a high level of more than 10us to trig pin to trigger module ranging. When the ranging is finished, the echo pin will output a high level, and the level width is the sum of the ultrasonic round-trip time.
