HC-SR04 is a wide range voltage work ultrasonic distance measurement module.Module size and the software is fully compatible with the old version HC-SR04.Can be seamlessly switch with the old version HC-SR04 .
Characteristic Wide voltage operation: 5.5V With HC-SR04 software and hardware size is fully compatible Detecting distance:
5V: 2cm - 450cm
Detection angle: <15 Using industrial grade MCU, working temperature: -20 - 80 degrees Celsius
1: This module should not be charged connection, if you want to live connection, then let the module Gnd end connection first. Otherwise it will affect the module work.
2:When ranging, the area of the measured object is not less than 0.5 square meters, and to be as smooth as possible.
3: if the test surface is irregular or test remote objects,multiple measurements can be used to correct it.
