Ultrasonic Range Finder HRLVEZ-EZ3-MB1033

Introduction

The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, and low-cost are needed.This sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a package less than one cubic inch.

The EZ3 is a narrow beam sensor with good side object rejection. This sensor has slightly wider beam width than the HRLV-EZ4-MB1043 which makes it a good choice for when the HRLV-EZ4-MB1043 does not have enough sensitivity for the application.

This sensor line features 1-mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-of-sound temperature compensation. This ultrasonic sensor detects objects from 1-mm to 5-meters, senses range to objects from 30-cm to 5-meters, with large objects closer than 30-cm typically reported as 30-cm. The interface output formats are pulse width, analog voltage, and serial digital in either RS232 or TTL.
