Although I am NOT currently using the HOBO, I DID look at them as a DIY home weather possibility but (as I vaguely recall) their accuracies (especially %RH) weren't acceptable.
What setup of components are you using for that township system?
Here you go:
RX3003 datalogger (the 10-year old system originally had a U30, but they are no longer supported by cell carriers)
S-THB-M002 12-Bit Temperature / Humidity Smart Sensor (better accuracy than previous older units)
S-LIB-M003 Solar Radiation Smart Sensor (silicon pyranometer)
S-BPM-CM50 Barometric Pressure Sensor
S-RGA-M002 0.01" Rain Gauge Smart Sensor
S-WCF-M003 Davis Wind Speed / Direction Sensor
A 6 watt solar panel keeps the battery charged. The accuracy and other specs are in the data sheets and manuals on the Onset website.
