Looking for a distance sensor that can be chained via an I2C communication bus and rated to be used outdoors? Solarbotics now offers the I2CXL-Maxsonar-WR Ultrasonic Sensor by Maxbotix that is I2C chainable and IP67 rated.

Description [Hide]

The I2CXL-MaxSonar-WR is a weather resistant sensor designed for outdoor detection and ranging. It is also has an I2C bus interface which is perfect for up to 127 sensors operating on a single bus interface for multi‑sensor operation.

The weather resistant I2CXL-MaxSonar-WR is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PCV pipe fittings.

High output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms results in virtually noise free distance readings. This holds true even in the presence of many of the various acoustic or electrical noise sources. The I2CXL‑MaxSonar‑WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long range detection zones.


  • 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
  • Long range, narrow detection zone
  • 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 3.4mA average current requirement
  • Operational temperature from -40˚C to +70˚C (-40˚F to +160˚F)
  • 200,000+ hours mean time between failure
  • Weather resistant IP67 rating
  • Matches standard electrical 3/4" PVC pipe fittings for easy mounting
  • RoHS compliant
