-Initially, the Solar Radiation / UV interface was designed to allow Weatherduino ​weather stations to have Solar Radiation ​and UV Index data at very low cost, using a small photovoltaic panel as solar radiation ​sensor. The concept is based on an article ​from Charles G. Wright, entitled [[http://​chuck-wright.com/​projects/​pv-measure.html|Measuring Solar Radiation]].\\ +Initially, the Solar Radiation / UV interface was designed to allow WeatherDuino ​weather stations to measure solar radiation ​and UV Index data at very low cost, using a small photovoltaic panel as sensor.

-Despite its simplicity, a solar radiation sensor based on a photovoltaic panel works quite well, and its readings are quite comparable to those from expensive pyranometers.\\ +Despite its simplicity, a solar radiation sensor based on a photovoltaic panel works quite well, and its readings are comparable to those from expensive pyranometers.\\ 
-Besides its initial goal, the Solar Radiation / UV interface can also be used with commercially available pyranometers, ​since its output voltage ​don'​t ​exceed 1.1V. An already ​tested ​model is the [[https://​www.apogeeinstruments.com/​sp-110-ss-self-powered-pyranometer/​|Apogee SP-110 Pyranometer]].\\+The Solar Radiation / UV interface can also be used with commercially available pyranometers, ​provided their output voltage ​does not exceed 1.1V. This has been tested ​with the [[https://​www.apogeeinstruments.com/​sp-110-ss-self-powered-pyranometer/​|Apogee SP-110 Pyranometer]].\\
 For UV index, we have chosen to use the UVM-30A UV sensor. For UV index, we have chosen to use the UVM-30A UV sensor.

-<WRAP round important 75%> Installing the photovoltaic panel and the UV sensor in a suitable housing, capable of resisting to atmospheric elements for long time may not be so easy as it may seem.\\ +<WRAP round important 75%> Installing the photovoltaic panel and the UV sensor in a suitable ​weatherproof ​housing ​is not straightforward.\\
