This ultrasonic range finder (MB1212) from Maxbotix has an I2C bus which allws for easy integration and multisensor operation using a single bus.
The I2CXL‑MaxSonar‑EZ1 offers a lower hardware gain and a smaller, narrower detection zone than the MB1202. This makes the I2CXL-MaxSonar-EZ1 a great choice for people detection applications.
The sensor is small in size, yet the high output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and real-time noise rejection algorithms results in virtually noise free distance readings for most users. This holds true even in the presence of many of the various acoustic or electrical noise sources. The I2CXL‑MaxSonar‑EZ sensor line is factory calibrated to match the sensor beam patterns and provides a long range detection zone.
