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:
Professional demodulation and ranging chip RCWL-9206
Support GPIO, UART and IIC three mode interfaces
3V-5. 5V wide voltage power supply
2. 2mA working current
2cm minimum blind area
The default software and hardware are fully compatible with the old version HC-SR04
Ultra-wide measuring range of 2cm-450cm (measuring flat walls)
The periphery is more concise
