Ultrasonic Range Finder - XL-MaxSonar-WR

This is the new, weather resistant, field-hardened WR from Maxbotix. The XL series of this sensor features higher resolution, longer range, higher power output and better calibration.

The WR uses a robust PVC housing, is designed to meet IP67 water intrusion, and matches standard electrical 3/4" PVC pipe fittings. The sensor provides very accurate readings from 0 to 765cm (0 to 25.1ft) with 1cm resolution. This sensor can be powered with anywhere between 3.3 and 5VDC.

Range information can be gathered through one of three methods - analog, serial, or PWM - all of which are active at the same time. The analog output will produce a voltage proportional to the measured distance, with a sensitivity of (Vcc/1024)V/cm. The serial interface is simple and formatted to RS-232, with voltages ranging from 0 to Vcc and terminal settings of 9600-8-N-1. Finally, the PWM pin outputs a pulse-width representation of the range with a scale factor of 58us/cm.

  • 3.3V to 5V supply with very low average current draw
  • All interfaces are active simultaneously
    • Serial, 0 to Vcc
    • 9600 baud, 8-N-1
    • Analog, (Vcc/1024) / cm resolution
    • Pulse Width
  • High acoustic power output
  • Real-time auto calibration and noise rejection for every ranging cycle
  • Precise narrow beam
  • Continuously variable gain
  • Object detection includes zero range objects
  • Readings can occur up to every 100mS, (10-Hz rate)
  • Free run operation can continually measure and output range information
  • Triggered operation provides the range reading as desired
  • Sensor operates at 42KHz

Ultrasonic Range Finder - XL-MaxSonar-WR Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels


Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Are you able to scan through substances other than air with these ultrasonic sensors?

      Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

      That being said, I have heard of the ultrasonic sensors being used with other fluids, but you would probably have to modify component for the environment (i.e. waterproof it if needed) and calibrate the readings for the fluid it interacts with.
