Operations and Timing Continued

Sensor Operation - Free-Run

When operating in free run mode, the HRLV-MaxSonar-EZ sensors are designed to be used in a variety of indoor

environments. Many acoustic noise sources will have little to no effect on the reported range of the HRLV-MaxSonar-EZ

sensors.

Most range readings are accurately reported. If the range readings are affected, the effect is typically less than 5-mm. This

allows users to employ real-time ultrasonic distance sensing without the need for additional supporting circuitry or

complicated user software.

Filtered Operation - Free-Run

The HRLV-MaxSonar-EZ uses an internal 2Hz bandwidth filter to process range data; which reports the latest range every

100mS or 10Hz. This improves the sensor’s performance for accuracy, noise rejection, and reading to reading stability.

The filtering in the free-run operation also permits additional acoustic and electrical noise tolerance.
