  • Maxbotix MB1222 I2CXL-MaxSonar-EZ2
  • Features a High-Performance Ultrasonic Sensor Module
  • Resolution of 1 cm
  • Offers a Reading Rate of up to 40 Hz
  • Simple I2C bus interface

The Maxbotix MB1222 I2CXL-MaxSonar-EZ2 High-Performance Ultrasonic Sensor Module features a centimeter resolution, an excellent compromise between sensitivity and side object rejection, short to long distance detection, range information from 20 to 765 cm, up to a 40 Hz read rate, and an I2C interface.

This makes the MB1222 is a great choice for applications that require decreased sensitivity to side objects than the MB1212.

The MB1222 from the I2CXL‑MaxSonar‑EZ line of sensors is a very small, less than one cubic inch, ultrasonic sensor component module. This sensor comes with mounting holes provided on the circuit board for easy installation in nearly all applications.

In addition, the MB1222 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.

Customer Reviews

Based on 2 reviews
Reliable ultrasonic sensor with convenient I2C interface

A reliable sensor working from 3V and up to 5V. The I2C interface makes it a good choice for applications in which several sensors might be connected to a single MCU. Also a good choice for battery operated devices.

A good choice for Raspberry Pi

There are no many ultrasonic sensors that use 3.3 V power supply, like this one. It works well with Raspberry Pi and gives accurate measurements. It would be even better if it could measure distances smaller than 20 cm, but at least it reports less than 20 as 20.
