Noise Tolerance
Different applications require different sensors. MaxBotix Inc. has divided our product lines into a series of products with varied sensitivity and maximum range to allow you to select the best sensor to meet your needs.
The diagram above shows how each product balances sensitivity and noise tolerance. To view how each sensor will function to different sized targets reference the I2CXL‑MaxSonar‑EZ Beam Patterns.
Reliable Ultrasonic Sensors
The industrial I2CXL‑MaxSonar‑EZ products are a high quality for cost indoor ultrasonic distance sensors. They provide an industrial component module solution that offers easy to use outputs, virtually no sensor dead zone, calibrated beam patterns, stable range readings, low power demands, and a host of other features as detailed in the product datasheets.
The Noise Filtering
The sensor dynamically adjusts its sensitivity to compensate for outside electrical & acoustic noise sources.
The Interface
The I2CXL‑MaxSonar‑EZ interface was designed to be very easy and intuitive to use. The interface uses a simple I2C command set. Using the I2C bus, a user can control up to 127 sensors over two wires.
The Power Requirements
The I2CXL‑MaxSonar‑EZ functions throughout a 3.0V to 5.5V operational voltage range. This allows for easy integration at either 3.3V or 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 I2CXL‑MaxSonar‑EZ sensors have a 4.4mA average current draw at 5.0V and 2.7mA average current draw at 3.3V.
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 I2CXL‑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 I2CXL‑MaxSonar‑EZ product line the product with the widest beam is the MB1202. The product with the narrowest beam is the MB1242.
The Calibration
Each I2CXL‑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 I2CXL‑MaxSonar‑EZ automatically calibrates to its environment before every range reading. This calibration includes compensation for voltage, humidity, acoustic noise, and electrical noise conditions. Temperature compensation for speed of sound changes are not applied.
The Sensitivity to Match Your Application
All users are encouraged to select the lowest sensitivity sensor that still easily matches their target size and distance detection requirements.
For people detection applications: Internal testing of our product shows that people typically have a detection pattern between that of a 6.35mm (1/4-inch) dowel and a 25.4mm (1-inch) dowel.
The MB1212 offers the best balance and is the sensor we recommended for a variety of applications.
Users concerned with only detecting large objects may want to select a sensor with a lower sensitivity such as the MB1232 or MB1242.
Users that desire a wide beam product and wish to detect smaller targets or people to longer distances should choose the MB1202 or the MB1212.
Reference the product datasheets or the I2CXL-MaxSonar-EZ Beam Patterns to get detailed information on how each sensor operates to different targets.

Custom Solutions
For some of our customers our standard products have not fit the requirements of their particular application. As a result, we have designed and manufactured a number of custom solutions. Some of the product improvements and features have been incorporated directly into our standard products. For other users we have evaluated their specifications and charged a small NRE fee for their custom parts.
Contact MaxBotix Inc. with your application and its requirements and our engineers will work to arrive at a desirable solution.
