Ultrasonic Range Finder HRXLWR-WRS-MB7384

Introduction

The weather resistant HRXL-WRS-MB7384 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.

The HRXL-WRS-MB7384 is a low-cost, rugged ultrasonic snow depth sensor that is optimized for reliable snow depth measurement. Internally, multiple sensor readings are analyzed using algorithms optimized for snow measurement, ensuring accurate snow depth measurements. The sensor accurately applies temperature compensation to every reading.

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 50-cm to 500cm. Objects closer than 50-cm are typically reported as 50-cm. The interface output formats are pulse width, analog voltage, and digital serial in RS232.
