Stuart,
1. Initially I have the Greenhouse sensor out of direct sunlight at the
top/front inside the greenhouse. This is then shielded from any direct
reflections by a piece of bent aluminium.
2. My angle on it is that as long as it stays dry, then it doesn't need
keeping out of the wind. My outside sensor is protected by mounting it
inside a stack of dished aluminium sheets, each with a 10mm hole in the
middle. The top one has been left un-drilled so as to form a cap. This
stack, something like a pagoda, allows plenty of ventilation without any
direct heat/light path to the sensor.
3. Again, this sensor is currently just "sheltered" from the wet.
Regards,
Jon

Have you weather proofed the external sensors? I'm looking at putting one
outside, but I'm stuck at the moment figuring out how to weather proof it.
These are the thing I'm mulling over...
1) It shouldn't be in direct sunlight. As Nigel saw with my indoor graphs
:-)
2) It should be out of the wind.
3) How to stop it getting wet.
