The LV-MaxSonar-EZ Sensors At a Glance

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

**Note: our XL‑MaxSonar‑EZ Products have both greater sensitivity

and far greater noise tolerance. View how the XL‑MaxSonar‑EZ products function to a given size target with the XL‑MaxSonar‑EZ Beam Patterns.

Easy to Use Ultrasonic Sensors

The original LV‑MaxSonar‑EZ products were the first low cost ultrasonic distance sensors to provide a component module solution that offered 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.

As a result, our component modules have found a wide acceptance in the robotics community, and have also been integrated into a number of industrial solutions including: proximity sensors for store displays, high speed sensors for vending machines, remote monitoring sensors for parking monitors, and distance sensors used to evaluate people's height.

The Interface

The LV‑MaxSonar‑EZ interface was designed to be very easy and intuitive to use. The interface output formats included are pulse width output, analog voltage output, and asynchronous RS232 serial digital output. All interfaces work without user code or complicated setup strings.

The Power Requirements

The LV‑MaxSonar‑EZ functions throughout a 2.5V to 5.5V operational voltage range.  This allows for easy integration at either 3.3V or 5V which 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 LV‑MaxSonar‑EZ sensors have a 2mA 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 LV‑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 LV‑MaxSonar‑EZ product line the product with the widest beam is the MB1000. The product with the narrowest beam is the MB1040.

The Calibration

Each LV‑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 LV‑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.

Industrial users may want to consider upgrading to the XL‑MaxSonar‑EZ Products to take advantage of the real‑time automatic calibration and the added clutter & noise rejection.
