The RangeWizard™ was developed to offload the timing overhead required to query the popular robotic ultrasonic based sensors, such as the MaxSonar‐EZ line and Devantech SRF sonars. This frees your microcontroller and or other controller (e.g. PC104, PC, Laptop) to use valuable interrupts and CPU cycles to perform other timing functions. The RangeWizard™takes care of all of the sensor timing, and can report the readings in microseconds, inches, or centimeters.

The RangeWizard™has the ability to query up to 10 ultrasonic sensors, and 6 analog sensors. The ultrasonic/sonar modules can be the single control line type like the Parallax Ping, or the trigger/echo type like the Max Sonar EZ line.

Additionally, there are 6 analog lines which can be used for any 5V analog senors, like the Sharp line of infrared sensors. Since the MaxSonar‐EZ ultrasonic sensors feature an analog interface, you can connect 6 additional sensors to the analog port, giving you the ability to query up to 16 MaxSonar‐EZ sensors.
