## Description

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. Key Features Ultrasonic Vehicle Detection – 42 kHz sensor with 500–5000 mm range USB Micro-B Interface – Simple plug-and-play connection Weather Resistant – Designed for outdoor and exposed installations Factory Calibrated – Matched beam patterns for reliable detection zones Advanced Noise Rejection – Variable gain, real-time calibration, and waveform analysis Multi-Sensor Operation – Supports multiple sensors in the same environment Preset Proximity Zone – 150 cm default detection zone Specifications Sensor Type – 42 kHz ultrasonic Range – 500–5000 mm Minimum Range – Objects closer than 500 mm typically read as 500 mm Proximity Detection Zone – 150 cm (preset) Read Interval – ~250 ms (~4 Hz) Target Acquire Time – ~4 seconds Target Release Time – ~5 seconds Interface – USB Micro-B Ideal For Drive-through vehicle kiosks ATM and bank drive-through lanes Parking detection systems Automated vehicle sensing Package Contents 1× MB8450 Car Detection Sensor Resources MB8450 Datasheet (PDF)
