[Palmyweather]

To a lot of people, the temperature sensor is one of the most important part of their weather station and is often in discussion on how to keep it as accurate as possible.

For me, this was also important. As I had an abundance of Fine Offset weather station parts, I thought I would use the radiation shield supplied. As you can see in the photos, I screwed the bracket through the top of the radiation shield and sealed it up, this also provided an easy and clean access point for the cable to enter.

I used a SHT10 temperature sensor which I covered with expanded white sound dampening carpet (similar to what cotton-wool is but will last/durable) to help protect the sensor form build up of dirt and hopefully keep it more accurate as time goes on. I carefully bent the cable so that the sensor would sit suspended in the middle of the radiation shield, not touching any plastic and with good airflow around it.

The 40mm fan fitted nicely with a bit of hot glue in the bottom. I chose to blow air into the radiation shield from the bottom as this would hopefully stop heat build up in the top of the cover.

I can mount my temperature sensor two ways, directly on the mast of my transmitter, or to make it more accurate, I have attached it to the cool/sun free side of the house for best results.

To achieve this I built a 10m (33 feet) extension fly-lead with the harsh environmental plugs I used on the outside of the transmitter box. The cable I used is double shielded with braid and foil wrap to cut down on any interference, the same type I used on all my other sensors. I was sceptical that this would work, but it has not missed a beat so far.

Hope this gives some ideas for others in their development of this project.
