DYP-A13NYUW-V1.0 Ultrasonic Sensor Module - UART Auto Output, 25-200cm Range

This module uses a UART (Universal Asynchronous Receiver/Transmitter) TTL serial interface for automatic output. It transmits distance data as serial bytes, which can be directly read by microcontrollers like Arduino, ESP32, or Raspberry Pi using standard serial libraries (e.g., Serial.read()). No pulse timing or echo pin handling is required.

The sensor operates on a wide DC voltage range from 3.3V to 24V. This makes it compatible with both 3.3V and 5V logic systems commonly found on development boards, as well as higher voltage industrial power supplies up to 24V. Ensure your power source is stable and within this range.

The sensor has a blind zone from 0 cm to approximately 25 cm. Objects placed within this range may not be detected reliably or may return inaccurate measurements. For stable operation, the target should be positioned beyond 25 cm, within the specified 25-200 cm measurement range.

Yes, the module features internal temperature compensation, which corrects for the speed of sound variations with air temperature. This ensures stable and accurate distance readings across its full operating temperature range of -15°C to +60°C, making it suitable for both indoor and outdoor environments.

Connect the module's VCC to 5V (or 3.3V), GND to GND, and the TX pin to an RX pin on your Arduino (e.g., digital pin 0 or a SoftwareSerial pin). Use the Serial or SoftwareSerial library to read the incoming data. The sensor automatically sends distance values, so your code only needs to parse the serial data stream.
