Ultrasonic Range Finder XL-MaxSonar-EZ2
The XL-MaxSonar-EZ2 is recommended for indoor use. It offers the best balance between wide or narrow beams and provides a good balance between small and large target detection. The XL-MaxSonar-EZ2 works for nearly all indoor applications including: people detection, large-target detection, long-range detection, applications requiring high noise tolerance.
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 MaxSonars are a super high-performance version of the easy-to-use sonar range finder from Maxbotix. 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. This sensor can be powered with anywhere between 3.3 and 5VDC.
Range information can be gathered through one of three methods - analog, serial, or PWM - all of which are active at the same time. The analog output will produce a voltage proportional to the measured distance, with a sensitivity of (Vcc/1024)V/cm. The serial interface is simple and formatted to RS-232, with voltages ranging from 0 to Vcc and terminal settings of 9600-8-N-1. 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.
Note:The Maxbotix Ultrasonic Sensors are now fully CE certified.
