The HRLV-MaxSonar-EZ products are high resolution ultrasonic 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.


  • 1mm(0.04") Resolution

The HRLV-MaxSonar-EZ Sensors offer calibrated 1 mm accuracy of 0.1% at 1 meter(39.37").

  • Internal Temperature Compensation

The speed of sound in air increases about 0.6 meters per second, per degree centigrade. Because of this, each HRLV‑MaxSonar‑EZ is equipped with an internal temperature sensor which allows the sensor to apply a compensation for speed of sound changes.

With the internal temperature sensor, range readings immediately (within twenty seconds) after power up are the most accurate, and this is ideal for battery applications where the sensor is powered off most of the time. The self heating (15mW at 5V, or 8mW at 3.3V) will change the temperature of the sensor by 3 degrees C or so. (The amount of self heating is also slightly dependent upon user mounting). As such, self heating will cause the sensor to read the actual air temperature inaccurately.

  • External Temperature Sensor

With the HR‑MaxTemp connected to the HRLV‑MaxSonar‑EZ line of sensors, realtime automatic temperature compensation is available. The HR-MaxTemp allows the HRLV‑MaxSonar‑EZ sensor to monitor the changes to air temperature while ignoring self-heating.

Self-heating is an issue with internal temperature sensors, where the temperature increase is typically 2 to 5 degrees centigrade. If ignored this will cause a drift of the reported of up to 3%.

The HRLV‑MaxSonar‑EZ is designed to used alongside the HR‑MaxTemp temperature sensor. On power-up the HRLV‑MaxSonar‑EZ will automatically detect an attached temperature sensor and begin to apply temperature compensation for the speed of sound changes to all range outputs.

  • The Interface

The HRLV‑MaxSonar‑EZ interface is designed to be very easy and intuitive to use. The interface output formats included are pulse width output, analog voltage output, and asynchronous serial RS232 or TTL (using a soldered jumper) output. All interfaces work without user code or complicated setup strings.

The Power Requirements

The HRLV‑MaxSonar‑EZ functions throughout a 2.5V to 5.5V operation

  • The Power Requirements

The HRLV‑MaxSonar‑EZ functions throughout a 2.5V to 5.5V operational voltage range.  This allows for easy integration from 2.5V to 5.5V and means that users of low voltage microcontrollers, or those who wish to operate in solar or battery based systems do not have to provide an extra power supply for the sensor.

The HRLV‑MaxSonar‑EZ sensors have a 3.1mA average current draw during free ranging operation.

  • The Controlled Beam Shape

Similar ultrasonic products may have frequent side lobe detection and can even falsely trigger on objects behind or to the sides of the sensor. The HRLV‑MaxSonar‑EZ offers a controlled beam that is designed to reject small objects (clutter) outside of the central beam area and provides long range sensitivity without detecting frivolous or unwanted targets.

Users are encouraged to pick the product with the sensitivity that best matches their application.  In the HRLV‑MaxSonar‑EZ product line the product with the widest beam is the MB1003. The product with the narrowest beam is the MB1043.

  • The Calibration

Each HRLV‑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.

The HRLV‑MaxSonar‑EZ automatically calibrates to its environment before every range reading. This calibration includes voltage, humidity, acoustic noise, electrical noise conditions, and compensation for temperature.
