i want to use 20 pulse sensors(rain gauges) with cr6, what is the best way to do it ?
is it possible to connect i2c IO module to cr6 ?
This could get you most of the way https://www.campbellsci.com/sdm-io16
is it possible to use SDM-IO16 as 16 pulse input ?
From the specifications;
from SDM-IO16 spec.. "Maximum Pulse Measurement Interval 15.9375 s"
What this means ? that raingauge pulses(pulse interval usually more than 15s) are nort read?
Maximum Pulse Measurement Interval 15.9375 s
The pulse measurement interval is a limit for frequency measurement. You can count pulses over longer periods. Normally you would simply ask the interface for the pulse count total every minute or perhaps hour if measuring raingauge.
