I had a change of mind with the display. For me not only the immediate temperature is of interest but so are the maximum and minimum temperatures.
First thought. With a bit of extra coding and rearranging the display I came up with:
Top left, immediate temperature. Top right immediate percentage relative humidity.
Bottom left, maximum temperature, Bottom right, rainfall in mm.
Switched so the bottom left shows minimum temperature.
I put the sensor in the top of a freezer to check it showed negative temperatures OK.
Further thought. Do away with the humidity reading:
Now I have:
Top left, immediate temperature, Top right, total rainfall in mm
Bottom left, maximum temperature. Bottom right, minimum temperature.
I am quite pleased with the final layout. The whole thing draws less than 80mA.
Once cased the unit will have buttons to reset max / min temperature and rainfall. On my old home brew rain gauge I reset the count at the beginning of each month and I would probably want to reset max / min temp daily.
