The MB7139 from theط¢آ XL-TrashSonar-WRط¢آ line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing which meets the IP67 water intrusion standard and matches standard electrical 3/4inch PVC pipe fittings (this product has multiple housing options available).
Theط¢آ XL-TrashSonar-WRط¢آ sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
In addition, the MB7139 offers virtually noise free distance readings through the use of high-output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
