I2CXL-MaxSonar-WR Series Ultrasonic Rangefinders Product Description
The I2CXL-MaxSonar-WR ultrasonic sensor features an I2C interface. The sensors have high acoustic power output along with real-time auto calibration for changing conditions (voltage and acoustic or electrical noise) that ensure users receive the most reliable (in air) ranging data for every reading taken. The I2CXL-MaxSonar-WR low power 3V - 5.5V operation provides very short to long-range detection and ranging, in a tiny and compact form factor. The I2CXL-MaxSonar-WR will typically detect objects from 0-cm to 765-cm or 1068-cm (select models) (3-cm to 625-cm for the WRC) and provide sonar range information from 20-cm out to 765-cm or 1068-cm (select models) with 1-cm resolution. Objects from 0-cm (3-cm for the WRC) to 20-cm typically range as 20-cm.

I2CXL-MaxSonar-WR Series Ultrasonic Rangefinders Features
• I2C bus communication allows rapid control of multiple sensors with only two wires
• High acoustic power output
• Real-time auto calibration and noise rejection for every ranging cycle
• Calibrated beam patterns
• Continuously variable gain
• Object presence information up to the front face of the sensor (3-cm for the WRC). Range information starting at min. distance.
• 3V to 5.5V supply with very low average current draw
• Readings can occur up to every 25mS (40Hz rate) for up-close objects. 15Hz (10Hz for MB7066) rate for full range.
• Triggered operation provides a new range reading as desired
• Ultrasonic signal frequency of 42KHz
• Status pin available to determine sensor state
• Power-up address reset pin available
• Physical dimensions match other XL-MaxSonar-WR/WRC products
• -40°C to +65°C operation

I2CXL-MaxSonar-WR Series Ultrasonic Rangefinders Low Power Requirement
• Wide, low supply voltage requirements eases battery powered design
