	The Sonar Sensor is manufactured by Maxbotix.com. We have added a sensor cable and instructions on soldering the cable to the sensor. The Sonar Sensor is Ratiometric. Make sure that the ratiometric property is set to TRUE when programming the sensor. Each time after the LV-MaxSonar®-EZ1™ is powered up, it will calibrate during its first read cycle. The sensor uses this stored information to range a close object. It is important that objects not be close to the sensor during this calibration cycle. The best sensitivity is obtained when it is clear for fourteen inches, but good results are common when clear for at least seven inches. If an object is too close during the calibration cycle, the sensor may then ignore objects at that distance. The LV-MaxSonar®-EZ1™ does not use the calibration data to temperature compensate for range, but instead to compensate for the sensor ringdown pattern. If the temperature, humidity, or applied voltage changes during operation, the sensor may require recalibration to reacquire the ringdown pattern. Unless recalibrated, if the temperature increases, the sensor is more likely to have false close readings. If the temperature decreases, the sensor is more likely to have reduced upclose sensitivity. To recalibrate the LV-MaxSonar®-EZ1™, cycle power. For more complete specifications on the MaxSonar-EZ1, please visit www.maxbotix.com		The Sonar Sensor is manufactured by Maxbotix.com.

			===Interference===
	Since the beam width is fairly large and sound tends to reflect more than light, sonar sensors will interfere with one another if more than one is active in a sensor array. To avoid interference we recommend that you poll each sensor individually and only activate the specific sensor you are polling. That way you can activate one sensor, read the distance, and then deactivate it before moving to the next sensor. This will give you clean results. Perhaps the easiest way to achieve this is to take the power line from the sensor and connect it to a digital output of your InterfaceKit instead of the normal analog input power pin. This will allow you to toggle the power to the device and turn it on or off at will.
