HRLV-MaxSonar-EZ3 Ultrasonic Range Finder

Component Overview

Cost-effective solution where precision range-findings are needed
Sensor component allows users to lower the cost of their systems without sacrificing performance
42kHz Ultrasonic sensor measures distance to objects
RoHS compliant
Read from all sensor outputs: Analog Voltage, RS232 or TTL Serial, and Pulse Width
Virtually no sensor dead zone, objects closer than 30 cm will typically range as 30 cm
Resolution of 1 mm
Maximum range of 5000 mm (195 inches)
Tolerates outside noise sources
Operates from 2.5V-5.5V
Low 3.1mA average current requirement
10Hz reading rate
Small, light weight module
Designed for easy integration into your project or product
Operational Temperature from -15°C to +65°C (+5°F to +149°F)
Real-time automatic calibration (voltage, humidity, ambient noise)
Internal temperature compensation
Option external temperature compensation HR-MaxTemp
Firmware filtering for better noise tolerance and clutter rejection
Narrow beam and good side object rejection
Best for large object detection applications

Product Documentation

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