Looking for a distance sensor that can be chained via an I2C communication bus? Solarbotics now offers a line of chainable I2C Maxbotix Ultrasonic Sensors.

Description [Hide]

The I2CXL-MaxSonar-EZ sensors now feature an I2C bus. This allows for easy I2C integration and multisensor operation using a single bus.The I2CXL‑MaxSonar‑EZ3 has high noise tolerance and a narrow beam with more sensitivity than the MB1242. The I2CXL-MaxSonar-EZ3 also offers increased sensitivity and a longer detection distance for small and medium sized targets.

The sensor is small in size, yet the high output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and real-time noise rejection algorithms results in virtually noise free distance readings for most users. This holds true even in the presence of many of the various acoustic or electrical noise sources. The I2CXL‑MaxSonar‑EZ sensor line is factory calibrated to match the sensor beam patterns and provides a long range detection zone.


  • Simple I2C interface, easy control of multiple sensors!
  • Control up to 127 sensors using two wires
  • Cost-effective solution where centimeter precision range-findings are needed
  • Virtually no sensor dead zone, objects closer than 20 cm will typically range as 20 cm
  • Great for people detection applications
  • Small, light weight module, designed for easy integration into your project or product
  • Narrow beam sensor
  • Firmware filtering for better noise tolerance and clutter rejection
  • Real-time automatic calibration (voltage, humidity, ambient noise)


  • Resolution of 1‑cm
  • 42kHz Ultrasonic sensor measures distance to objects
  • Up to 40Hz reading rate
  • Maximum range of 7650 mm (301 inches)
  • Operates from 3.0V-5.5V
  • Low 4.4mA average current requirement
  • Operational temperature from -40˚C to +70˚C (-40˚F to +160˚F)
  • 200,000+ hours mean time between failure
  • RoHS compliant
