Description
Feature: HC-SR04 (2020 version) is an open ultrasonic ranging module with a size fully compatible with the old version and adding UART and IIC functions. By default, the software and hardware are fully compatible with the old version of HC-SR04; it can be set to UART or IIC mode through a resistor. 2CM blind zone, 4.5M typical longest distance measurement, 2.2mA working current. Using the upgraded demodulation chip RCWL-9206, MCU with UART and IIC functions; make the peripherals more concise, the working voltage is wider (3-5.5V), and the interface functions are more.Specification:
