Keyestudio RJ11 Easy Plug SR01 Ultrasonic Sensor Module V2.0( N76E003AT20) for Arduino Robot Car

The Keyestudio RJ11 Easy Plug SR01 Ultrasonic Sensor Module V2.0 is an easy-to-use distance-measuring sensor designed for robotics, automation, and interactive art projects. Featuring the upgraded N76E003AT20 solution and a simple RJ11 connection, it is ideal for students, hobbyists, and educators building Arduino-based robot cars.

Simple RJ11 connection

This module uses a double digital interface that connects with a single RJ11 cable, making wiring fast and error-free. It is designed specifically to match with the Keyestudio EASY plug control board.

Upgraded N76E003AT20 solution

The SR01 module integrates an ultrasonic transmitter, receiver, and control circuit into a single compact board. It features the upgraded N76E003AT20 processor for reliable performance in motion-sensing and obstacle-avoidance applications.

Convenient mounting holes

Equipped with four fixed mounting holes, this sensor can be easily secured to various structures. It is ideal for mounting on mobile platforms, such as a servo-driven plastic bracket on a robot car.

Precise distance detection

The sensor measures distances from a minimum of 2cm up to a maximum range of 2 to 3 metres. It operates with a measuring angle of 15 degrees for targeted detection.

Low-power electrical specifications

Operating at a standard DC 5V, the module draws a low operating current of 15mA. It runs at an operating frequency of 40KHz, ensuring stable acoustic measurements.

Compact and lightweight design

Measuring just 49mm by 25.4mm by 28mm and weighing only 10.4g, this sensor adds minimal bulk to your builds. It is perfect for small-scale mobile robots where weight and space are critical factors.

Comprehensive learning resources

To help students and makers get started quickly, a dedicated Wiki page tutorial is available. This guide assists with programming and integrating the sensor into your Arduino projects.
