Ultrasonic Range Finder HRXLWR-WRT-MB7380

Introduction

The weather resistant HRXL-WRT-MB7380 is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4-inch PVC pipe fittings.

High output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms results in virtually noise free distance readings. This holds true even in the presence of many of the various acoustic or electrical noise sources.

The HRXL-MaxSonar-WR sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, with an IP67 weather resistant rating.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 and optional external speed-of-sound temperature compensation.This ultrasonic sensor detects objects from 1-mm and ranges to objects from 30-cm to 500cm. Objects closer than 30-cm are typically reported as 30-cm. The interface output formats are pulse width, analog voltage, and digital serial in TTL.
