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

Liquid Level Sensing
Monitoring tank levels where the sensor must withstand high humidity and occasional splashes.
Outdoor Obstacle Avoidance
Providing distance data for autonomous mobile robots or vehicles operating in outdoor environments.
Smart Trash Bin Systems
Detecting fill levels in waste containers where the sensor probe is exposed to debris.
