August is supposed to be the silly season and so I have been doing silly things with my new Raspberry Pi.
What I have done is turned it into a temperature logging device which can be left in the MH and over a period it will measure the temeperaure in the MH and write it to a file. At the end I can take the file, load it into Excel and plot a graph showing how the temperature changed over, in this case, about 24 hours.
The graph above goes from about 3 o'clock on Saturday to about 3 o'clock on Sunday. The blip at the start of the graph is the device warming up as it was turned on. The vertical scale is of course degrees Celsius.
There is a serious side to this but it will have to wait for the winter. What I want to see is when the Webasto diesel heater is running how accurately does the thermostat hold the temperature? The reason is I suspect the temperature fluctuates quite a lot and this may be influenced by the position of the temperature sensor the heater uses as it is fixed to the wall near a small window in a corner. I have also noticed the temperature fluctuuations with the heater seem greatest i the first day or so of being switched on and after that, perhaps when the fabris of the MH has warmed up it seems to steady. The temperature logger I have made is software driven so I can set it to measure the temperature over several days if necessary.
I can add more temperature sensors to the Raspberry Pi and measure the temperature at floor level as well as say head hight.
However, it was interesting to see that the inside of the MH, parked outside with all the blinds drawn is going through at this time of year a daily temperature fluctuation of about twenty degrees.
