HC-SR04 ultrasonic ranging module ranging sensor/wide voltage 3.3V 5V -70273
product detail
HC-SR04 (version 2020) is an open ultrasonic ranging module with a size that is fully compatible with the old version and adds 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 1IC mode through resistance. 2CM blind zone, 4.5M typical longest distance measurement, 2.2mA working current. Use the upgraded demodulation chip RCWL-9206. MCU with UART and IIC functions; make the periphery more concise, wider working voltage (3-5.5V), and more interface functions.
