Maxbotix XL-MaxSonar-EZ4 High Performance Sonar Module

• Ranges from 20 cm to 765 cm
• Serial (0-Vcc), Analog voltage or pulse width interfaces
• 1 cm resolution
• Small size allows for easy mounting
• Hardware gain of 250

The Maxbotix XL-MaxSonar-EZ4 High Performance Sonar Module is a super high performance sonar range finder with high power output, noise rejection, auto calibration and short-range narrow detection zone (hardware gain of 250).

The tiny indoor XL-MaxSonar® sensor line are less than 1-cubic-inch in size, yet the sensor puts 1/2 watt of peak power into the efficient transformer driving the transducer, yielding high output acoustic power. This 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® sensor line is available with factory calibrated beam patterns and can be used anywhere an indoor acoustic range sensor is needed.

Features:

• High acoustic power output
• Real-time auto calibration and noise rejection for every ranging cycle
• Calibrated beam angle

• 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
• All interfaces are active simultaneously
• Serial, 0 to Vcc
• 9600Baud, 81N
• Analog, (Vcc/1024) / cm
• Pulse Width (MB1240)
• Real-time analog envelope (MB1340)
• Sensor operates at 42 KHz
