HRUSB-MaxSonar-EZ Ultrasonic Range Finder

Sensor Line

High Performance Ultrasonic Rangefinder
RoHs Compliant

The HRUSB-MaxSonar-EZ ultrasonic sensors feature an easy to use USB interface that connects directly to a computer with a standard Micro-B USB cable. The HRUSB‑MaxSonar‑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 HRUSB‑MaxSonar‑EZ detection zone.

The HRUSB‑MaxSonar‑EZ ultrasonic 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.

Noise Tolerance

Different applications require different sensors. The HRUSB‑MaxSonar‑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 HRUSB‑MaxSonar‑EZ  Beam Patterns.

Easy to Use Ultrasonic Sensors

The HRUSB‑MaxSonar‑EZ products are low cost ultrasonic range finding sensors that provide a component module solution that offers an easy to use output, 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 HRUSB‑MaxSonar‑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 HRUSB‑MaxSonar‑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 sensitivity that best matches their application.  In the HRUSB‑MaxSonar‑EZ product line the product with the widest beam is the MB1403. The product with the narrowest beam is the MB1443.

The Calibration

Each HRUSB‑MaxSonar‑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 HRUSB‑MaxSonar‑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.
