The HC-SR04+new model is based on the original HC SR04+ Upgraded ultrasonic ranging module. By default, the software and hardware are compatible with the original HC-SR04o, and UART has been added, IIC and 1-Wire (single bus) functions, modes can be set through peripheral resistors.
2CM ultra small blind spot, 4M typical max distance measurement, 2mA ultra-low I current, 2.8-5.5V ultra wide operating voltage. Adopting multi-level controllable gain amplification to avoid the influence of blind spots.
The driver adopts frequency scanning technology to reduce the impact of probe consistency on sensitivity. The internal 40K driving frequency adopts positive temperature compensation, which conforms to the temperature characteristics of the probe center frequency and reduces the impact of temperature on sensitivity.
Supports GPI0, UART, IIC, and 1-WIRE multiple interfaces; Mode, default output mode compatible with HC-SR04
Typical applications: Toys, robot obstacle avoidance, Liquid level, water level measurement, Sitting posture detection, Other ranging applications
