HC-SR04 is a wide range of ultrasonic working voltage measurement module distance. The module size and software are fully compatible with the old HC-SR04 version. It can perfectly break with the old HC-SR04 version. The lowest operating voltage as low as 3V allows it to be directly connected to a 3.3V power MCU.
Features
High working voltage: 3 V-5.5 V Fully compatible with software and hardware HC-SR04 size Detection distance: 5 V: 2 cm -450 cm 3.3 V: 2 cm to 400 cm Detection angle: <15 Using industrial-grade MCU, working temperature: -20-80 degrees Celsius
Notice: 1: The module does not need to be connected for charging. If you want to connect, connect the Gnd module to the terminal first. Otherwise it will affect the work of the form. 2: When they walk, the area of the measured object is not less than 0.5 square meters, and it should be as simple as possible. 3: If the test surface is irregular or the remote test object is tested, multiple measurement values can be used for correction.
