Description: 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.

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.

Features:

• 3.3V to 5V supply with very low average current draw
• High acoustic power output
• All interfaces are active simultaneously:
  • RS-232 serial
    • 0 to Vcc output range
    • 9600 baud, 8-N-1
  • Analog, (Vcc/1024) / cm
  • Pulse Width
• Real-time auto calibration and noise rejection for every ranging cycle
• Calibrated beam angle
• Object detection includes zero range objects
• Readings can occur up to every 100mS, (10-Hz rate)
• Free run operation can continually measure and output range information
• Triggered operation provides the range reading as desired
• Sensor operates at 42KHz
