Sensor Line

High performance USB ultrasonic proximity detection sensor
RoHs Compliant

The USB-ProxSonar-EZ ultrasonic proximity sensors feature an easy to use USB interface that connects directly to a computer with a standard Micro-B USB cable. The USB‑ProxSonar‑EZ sensors detect objects in a calibrated detection zone and report when an object (such as a person) enters the detection zone. The target is released after leaving the USB‑ProxSonar‑EZ detection zone.

The USB‑ProxSonar‑EZ ultrasonic proximity sensor provides a component module solution that offers easy integration with USB connectivity, no sensor dead zone, calibrated beam patterns, stable range readings, and a host of other features.

Different applications require different sensors. The USB‑ProxSonar‑EZ product line offers varied sensitivity to allow you to select the best sensor to meet your needs.

The diagram above shows how each product balances sensitivity and noise tolerance. This does not effect the maximum range, pin outputs, or other operations of the sensor. To view how each sensor will function to different sized targets reference the USB‑ProxSonar‑EZ Beam Patterns.

Easy to Use Ultrasonic Sensors

The USB‑ProxSonar‑EZ products are low cost ultrasonic proximity sensors that provide a component module solution that offers easy to use outputs, no sensor dead zone, calibrated beam patterns, stable range readings, low power demands, and a host of other features detailed in the product datasheets.

The Interface

The USB‑ProxSonar‑EZ interface was designed to be very easy and intuitive to use. The interface is an easy to use USB connection.

The Controlled Beam Shape

The USB‑ProxSonar‑EZ offers a controlled beam that is designed to reject small objects (clutter) outside of the central beam area without detecting frivolous or unwanted targets.

Users are encouraged to pick the product with the detection zone that best matches their application.  In the USB‑ProxSonar‑EZ product line the product with the longest detection zone is the MB1414. The product with the shortest detection zone is the MB1444.

The Calibration

Each USB‑ProxSonar‑EZ is tested for proper operation at our facility and comes with a factory calibrated beam pattern to help ensure consistent operation of the sensor even from part to part.

In addition to this, the USB‑ProxSonar‑EZ 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 whenever the voltage, temperature, or humidity conditions change.
