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.
We are extremely pleased with the size, quality, and ease of use of this little range finder. 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.
