WI-I/O 9-K

Example 2:
A system of tipping bucket raingauges is installed to monitor rainfall in a catchment area. Each
raingauge provides a pulse signal to a WI-I/O K - each pulse represents 1/100
th
inch of rain.
The user wants a transmission at each pulse. During dry periods or periods of light rain, the
number of transmissions are small - but during periods of heavy rain, there could be a pulse
every couple of seconds - because of the large number of raingauges, this could result in
jamming of the radio channel. To prevent this occurring, a paralysis time of 60 seconds is
selected.
