Description: These easy-to-use ultrasonic rangefinders from Maxbotix work the same way as the EZ line that you know and love, but this new high-resolution series features 1 millimeter resolution! As with the rest of the Maxbotix range finders, these sensors feature Analog Voltage, RS232 Serial, and Pulse Width outputs making them easy to interface with any microcontroller. These sensors have a maximum range of 5000 mm (195 inches) with virtually no dead zone (although objects closer than 30 cm will typically range as 30 cm).

We’re offering the EZ0, EZ1, and EZ4 with progressively narrower beam angles allowing the sensor to match the application. Please see beam width explanation below.

Control up to 10 sensors with only two pins! Checkout the Maxbotix FAQ listed below.


  • 42kHz Ultrasonic sensor
  • Operates from 2.5-5.5V
  • Low 3.1mA average current requirement
  • 10Hz reading rate
  • Analog Voltage, RS232 or TTL Serial, and Pulse Width
  • Small, light weight module

Customer Comments

  • I bought two of these devices, one EZ0 and one EZ4, just to compare the results. I took them out of their package and was about to wire them up, but now I don’t see anything on the unit that distinguishes the EZ0 from the EZ4! The two modules appear to be identical. Is there any way to tell the difference?

    • Oops… Just saw the “colored” dot info in the data sheet… I’m good to go. Tx

  • How much beam angle is it? Is the beam angle change with distance? If so, how much.


  • Did you mean a minimum range of 30 mm? Not 30 cm?
