This ultrasonic range finder (MB1210) from Maxbotix offers a lower hardware gain and a smaller, narrower detection zone than the MB1200.
This makes the XL-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 XL‑MaxSonar‑EZ sensor line is factory calibrated to match the sensor beam patterns and provides a long range detection zone.
The XL series of this sensor features higher resolution, longer range, higher power output and better calibration when compared to the LV version.
The sensor provides very accurate readings from 0 to 765cm (0 to 25.1ft) with 1cm resolution. Finally, the PWM pin outputs a pulse-width representation of the range with a scale factor of 58us/cm. The Maxsonar-XL series is offered in the EZ0, EZ1, EZ2, EZ3, and EZ4 versions, each with progressively narrower beam angles allowing the sensor to match the application. Please see beam width characteristic explanation below under datasheet XL-Maxsonar-EZ1.
