Current Cost energy monitor Development Board Solar sensing
Posted: Sat Jul 02, 2011 2:38 pm
I have been experimenting with a solar sensor made up of a Current Cost energy monitor analogue Development Board. The board has a couple of light dependant resistors added and a variable resistor.
The light dependant resistors are mounted in an old automatic light sensor box which is then clipped onto my wind mount sensor pole. They are then cabled down to my current cost board. Readings are then fed into my Current cost CC128 that is plugged into my meteohub as a 2nd weather station.
Using the preset I have set full sunlight to show as 21.9kWatt on my CC128. Meteohub sees this as a value of 21984.
The sensor are very sensitive and the "full sun" value drops even if a very very fine wispy cloud moves over the sun.
Using meteoplug I apply a multiplication factor of 0.00455 in the graph definitions to show a relative value of 100 for full sun.
see example test graph of light and temp https://www.meteoplug.com/cgi-bin/meteo ... ccdececaca
I will play around with the graphs on meteoplug and see if i can get a chart/table for hours of sunlight etc.
If anyone has any example charts or ideas of how best to implement this please let me know.
