super high-performance version of the easy-to-use sonar range finder from Maxbotix. This small range finder is high quality, and easy to use. 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.

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
