Features of the weather-resistant MB8450, Car Detection Sensor, include centimeter resolution, short to long-distance detection, range information from 500mm to 5000mm for the nearest detectable target, a ~4Hz read rate, and an easy-to-use USB interface.

The MB8450 Car Detection Sensor is a low‑cost vehicle detection sensor that uses ultrasonic technology for non-contact sensing. The MB8450 is designed to be an easy-to-use sensor for applications where vehicle detection is desired. This sensor is great for applications such as vehicle kiosks, ATMs, and bank drive-throughs.

The MB8450 is factory calibrated to match sensor beam patterns and provide reliable long-range detection zones.

In addition, the MB8450 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.
