==Introduction==
The EASY plug SR01 ultrasonic module needs to be used with the EASY plug Control board V2.0. The module is connected to the double digital port interface with only one line,which is very easy and convenient. This module includes ultrasonic transmitter, receiver and corresponding control circuit. The module comes with four round holes, so that customers can put the module to be fixed on other devices, such as the servo plastic platform and so on.<br>

EASY plug SR01 Ultrasonic Module


Introduction

The distance sensor are really common in robotics projects, very useful for automation, interactive art and motion sensing.
This EASY Plug SR01 Ultrasonic integrates ultrasonic transmitter, receiver and corresponding control circuit.
It should be connected to the double digital interface with only one line, which is very easy to use and convenient for connection.
The module comes with four fixed holes, so that can easily fix it on other devices, such as the servo plastic platform and so on.
This module should be used together with EASY plug control board.
