The Maxbotix HR-LV-MaxSonar-EZ4 High Performance Sonar Module is the narrowest beam width sensor that is also the least sensitive to side objects offered in the HRLV-MaxSonar-EZ sensor line. The HRLV-MaxSonar-EZ4 is an excellent choice when only larger objects need to be detected.

good sensor

I bought this sensor and it works very well in i2c. I use it connected to the Raspberry Pi in 3.3v. attention distance mini 20 cm

Works very well

Exactly as advertised. Didn't check actual overall accuracy but the step-size/resolution is accurate and fluid. Super easy to interface with using pulse-length method, I assume V_analog method would also work well but haven't tested it. Take your time selecting you model for the right beam width and side object sensitivity. Will be using again in other applications.

Great sensor!

I bought 5 of these sensors and they work great. I use them for for water tank level measurement hooked up to Raspberry Pi's.
