Operating Modes
Multiple Sensor Operation
Multiple HRLV-MaxSonar-EZ sensors can be used simultaneously in the same environment generally with little to no
interference (cross-talk). Even so, some cross-talk may still occur for users wishing to use a large number of sensors in
the same environment. This interference is rare and can be up to +/- 1 cm of the target’s distance. Because of this, sensor
to sensor interference must be accounted for. To avoid interference between sensors, chaining can be used to prevent
cross-talk between sensors. This will be necessary when using 3+ sensors depending on mounting and environment.
The recommended chaining method is AN Output Commanded Loop. The first sensor will range, then trigger the next
sensor to range and so on for all the sensors in the array. Once the last sensor has ranged, the array stops until the first
sensor is triggered to range again. Below is a diagram on how to set this up.
Another recommended chaining method is AN Output Constantly Looping. The first sensor will range, then trigger the
next sensor to range and so on for all the sensors in the array. Once the last sensor has ranged, it will trigger the first
sensor in the array to range again and will continue this loop indefinitely. Below is a diagram on how to set this up.
