DYP-A01ANYUB-V2.0 UART-Auto Ultrasonic Sensor 28–750cm

The DYP-A01ANYUB-V2.0 model (A01A/B variant) operates from 3.3V to 5.0V DC, making it directly compatible with most microcontrollers like Arduino and ESP32. For extended voltage operation, the A01C variant supports 5.0V to 12V DC. Ensure you select the correct variant for your system's voltage rail.

The sensor's UART interface operates in an auto-send mode, continuously outputting distance data packets. Simply connect the sensor's TX pin to your microcontroller's RX pin. The default baud rate is 9600 bps, and the data format includes a start byte, two data bytes for distance (high and low), and a checksum byte for verification.

Yes, the integrated ultrasonic transducer is sealed and features a protective bell mouth, making the module resistant to water splash and dust ingress. It is designed for reliable operation in harsh outdoor conditions, such as agricultural monitoring, outdoor robotics, and industrial tank level sensing.

This formula defines the measurement error. The '1 cm' is a fixed base error. The 'S * 0.3%' is a variable error proportional to the measured distance (S). For example, at 500 cm, the variable error is 500 * 0.003 = 1.5 cm, resulting in a total potential error of ±2.5 cm. This ensures predictable accuracy across its full range.

Yes, the A01A/B variant is designed for 3.3V to 5V operation, and its UART/PWM output signals are compatible with both 3.3V and 5V logic levels. For interfacing with higher-voltage industrial systems (5-12V), the A01C variant should be used, though its output signal level may require conditioning for lower-voltage microcontrollers.
