Car Detection Sensor(MB8450)

The MB8450 is a weather-resistant ultrasonic car detection sensor with centimetre resolution and a range of 500–5000 mm. It connects via USB Micro-B for simple interfacing and is factory calibrated for reliable long-range vehicle detection zones.

Designed for non-contact vehicle sensing applications such as drive-through kiosks, ATMs, and bank lanes. Advanced noise rejection — including continuously variable gain, real-time background calibration, and waveform signature analysis — delivers virtually noise-free distance readings even in acoustically or electrically noisy environments.
