Over the last week or so I disassembled and cleaned this sensor. I don't see any water damage but I can't get the LW junction board loose as it seems glued to the case. I totally replaced the four wires running between the LW and SW sides. These wires were broken after having been previously broken and spliced. I soldered new wires directly to the junction boards. I collected about two days of data on the window sill with the sensor partially disassembled so that all four sensors could point up together. The relationship between the paired sensors was very tight (r-squared >0.99) - excluding a portion of the LW data that might have been affected by solar heating. LW had a sloped of 1.01 but SW had a slope of 1.20 - new calibration coefficients are probably needed. Today I completely reassembled the sensor and put it out the window on a boom to collect some data to check the assembly. |
