Ultrasonic Car Detection Sensor MB8450

Introduction

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 thru’s.

The MB8450 Car Detection Sensor provides a component module solution that offers an easy to use interface, calibrated beam patterns, stable range and proximity information, and a host of other features detailed in the product datasheets.

The Interface

The MB8450 Car Detection Sensor interface was designed to be easy and intuitive to use. The interface is an easy to use Micro-B USB connection, the same connection used on many smartphones.

The Controlled Beam Shape

The MB8450 Car Detection Sensor offers a controlled beam that is designed to reject small objects (clutter) outside of the central beam area without detecting frivolous or unwanted targets.

The Calibration

Each MB8450 Car Detection Sensor is tested for proper operation at our facility and comes with a factory calibrated beam pattern to ensure consistent operation of the sensor even from part‑to‑part.

The MB8450 Car Detection Sensor automatically calibrates to its environment after power up, before taking the first reading. Because this power up calibration only occurs on power up, it is recommended that users power off and then on the sensor when temperature or humidity conditions change.
