Is this enough to make a replacement for the Temp/RH sensor of the VP2+?
Any additional device (type) specs required or is this enough?

That's enough. I used one based on an SHT75 until I replaced it with a Davis SHT31.

Perhaps you also have the equivalent for Sun and Uv ? :roll:
Sun and UV-I are the same...
2 - Yellow - +V
3 - Green - signal
4 - Red - Ground
5 - Black - Ground

Hi,
Does someone know the signal scale for Sun and UV ?
Thanks

Here you go...

0V = 0 UVI
zero offset = 70mV = 0 UVI
2.395V = 16 UVI
3V = 16 UVI
step per 0.1 UVI = 14.3mV

Google is your friend ;)
But...
0V = 0 W/m2
~1.67V = 1000 W/m2
2.977V ~ 1780 W/m2
step per W/m2 = 1.67mV
