DFRobot A02YYUW Waterproof Ultrasonic Sensor
Overview
The SEN0312 is a waterproof ultrasonic distance sensor designed for reliable performance in harsh environments where dust or moisture may be present. It provides a measurement range of 28cm to 450cm and outputs data via a UART interface for easy integration with microcontrollers.
Why Choose This Part
The sensor features a closed, waterproof probe design that protects the transducer from environmental contaminants. It operates at a consistent 5V supply and offers a low 8mA average current draw, making it suitable for battery-powered remote monitoring applications.
Applications
Key Specifications
Getting Started
Connect the 4-pin interface to a 5V power source and a microcontroller UART port (TX/RX). Read the serial data packets at the sensor's default baud rate to extract distance measurements in millimeters.
