UV, radiation, and illuminance are three different things. some stations measure illuminance, then convert to radiation. some measure radiation. measuring uv requires a different sensor. there are conversion factors to go between illuminance and radiation, but those are gross approximations. uv index is arbitrary. davis hardware uses a 0-16 integer scale. rainwise uses something else. ukmet uses something else. > radiation = radiation * 0.731 > your hardware might be reporting luminance, not radiation. check the hardware specs to see exactly what kinds of sensors it has. does it have just illuminance, then it is fabricating a UV index and a radiation value? or does it actually measure UV? once you know exactly what the hardware is capable of doing, then we can see how that maps to the packets that the interceptor driver is receiving from it. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
