We decided to try the SP510. Seems to work fine with the ADS1115 set to max gain (GAIN_SIXTEEN) with differential measurement. Resolution is 7.8 uV, or 0.14 W m^-2. I ran it for a few days logging every 2 seconds and it doesn’t look especially noisy. We will be trying this out more thoroughly in the coming month.

We want to monitor solar radiation (shortwave) under forest canopy, for which common silicon diode pyranometers (e.g. Apogee SP212) are not suitable – a thermopile pyranometer is needed. We have two options for thermopile pyranometers. 1) Apogee…[Read more]
