Ultrasonic Range Finder I2CXLEZ4-MB1242

Introduction

The I2CXL-MaxSonar-EZ sensor allows for easy I2C integration and multisensor operation using a single bus. The sensor have high acoustic power output along with real-time auto calibration for changing conditions (voltage and acoustic or electrical noise) that ensure users receive the most reliable (in air) ranging data for every reading taken.

The I2CXLEZ4-MB1242 has highest noise tolerance and narrowest beam of any of our indoor sensors. The sensor is designed and calibrated to provide reliable range information to large targets even in environments with strong acoustic or electrical noise sources.

This sensor provides very short to long-range detection and ranging, in a tiny and compact form factor. It detect objects from 0-cm to 765-cm (25.1 feet) and provide sonar range information from 20-cm out to 765-cm with 1-cm resolution. Objects from 0-cm to 20-cm typically range as 20-cm.

Note: Object from 0-mm to 1-mm may not be detected.

Multiple Sensor Reference Wiring Diagram
Adding additional sensors to the I2C bus is extremely simple, as long as each sensor is programmed first to a different address, and the bus capacitance is low enough for the pull-up resistors to work properly. GND, V+, SCL and SDA simply need to be connected to the existing wires that the bus operates on. Each sensor can then be addressed individually to perform a range finding cycle or return the range data.
Note: For more detail refer datasheet.
