Ultrasonic Range Finder XL-EZ2 MB1220

Introduction

EZ2 (MB1220) sensor has high power output along with real-time auto calibration for changing conditions (temperature, voltage and acoustic or electrical noise) that ensure you receive the most reliable (in air) ranging data for every reading taken. The MB1220 consumes very low power at 3.3V – 5.5V and operation provides very short to long-range detection and ranging, in a tiny and compact form factor. The MB1220 detect objects from 0-cm to 765cm (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. The interface output formats included are real time analog voltage envelope, analog voltage output and serial digital output.
To select correct sensor for your application refer to Sensor Selection Guide

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