Hidden Canyon dataloggers
There are two Campbell CR23x dataloggers at Hidden Canyon:
- Met1 is located on the met towerand it logs meteorological data and powers the modem and the Base and Met1 radios.
- Forest1 is located on the forest towerand it logs meteorological data and soil profiledata (via 3 multiplexers).
Both of these dataloggers are connected via radio to the communications system.
