Description: HC-SR04-P is a wide range of ultrasound working voltage measuring module distance. Module size and software is fully compatible with the old HC-SR04 version. It can be perfectly interrupted with the old HC-SR04 version. Low to 3V minimum operating voltage, so that it can be directly connected to the 3.3V powerMCU. Feature High operating voltage: 3 V-5.5 V With software and hardware HC-SR04 size is fully compatible Detection distance: 5 V: 2 cm-450 cm 3.3 V: 2 cm to 400 cm Detection angle: <15 Use of industrial grade MCU, operating temperature: -20-80 degrees Celsius Note: 1: This module does not have to be charged connection, if you want to live connection, then let the Gnd module end connection first. Otherwise it will affect the form's work. 2: When they go, the area of the measured object is not less than 0.5 square meters, and to be as easy as possible. 3: If the test surface is irregular or remote test objects, multiple measurements can be used to correct it.
