Ultrasonic Sensor Platform Evaluation Expansion Board
Active1,021 in stock

Overview

The DFRobot SEN0311 is a waterproof ultrasonic distance sensor designed for reliable performance in harsh environments. It features a separate probe design with an IP67 rating, providing an automated UART output for distance measurements ranging from 3cm to 450cm. Operating at 3.3V to 5V with a low current draw of less than 8mA, it is ideal for outdoor or industrial sensing applications.

Why Choose This Part

The sensor features a waterproof and dustproof IP67 probe, making it resilient against environmental contaminants. It simplifies integration by providing a processed UART signal, and its low power consumption of under 8mA makes it suitable for battery-operated deployments.

Applications

Automotive Obstacle Detection
Used as a backing car annunciator or proximity sensor for vehicles and heavy machinery.
Outdoor Robotics
Provides obstacle avoidance for robots operating in damp or dusty environments where standard sensors might fail.
Object Approach Detection
Monitoring approaching objects in industrial automation or security systems with a wide operating temperature range of -15C to 60C.

Function Ultrasonic

Getting Started

Connect the four-wire interface (VCC, GND, RX, TX) to any microcontroller with a UART port, such as an Arduino or Raspberry Pi. The sensor automatically outputs distance data in millimeters over the serial line at a default baud rate of 9600. Ensure the probe is mounted securely using the included bracket to maintain consistent alignment.
