Greenroof Data Verification and GreenCamera Website – by Logan Gerber-Chavez

On September 25, we split in half again for those programming to work on the code improvements again while the roof group worked on troubleshooting problems with the equipment.

With the installation of the lightning rod we determined we would have to drill a hole in the pipe to fit the lightning rod on the top of the weather station.  The datalogger we installed last week was also not working, we suspected a short in the box but found that a fuse had burned out. We had to rearrange some of the wiring based on the new program code applied. Finally we had both Greenroof 1 and Greenroof 2 functional and delivering data.

The data from Greenroof 2 was streaming but we weren’t sure if the probes were labeled the way they were supposed to be. Our method of verification was to pull the probes out and put them in the shade one by one hoping to see a temperature difference. We saw #3 go change 1.3 degrees after 5 minutes which didn’t seem to be conclusive. We decided to bring ice water next week to individually test each probe to verify the correct label placement.

The greenroof camera website is up and accessible!

Today, we installed the new fuse and the second group worked on formatting the website with tabbed data for soil moisture, soil temperature, and meteorological data in time series.

The roof half worked on verifying probe labels with ice water.

From our experiment, all of the probes were labeled correctly according to the following labels.
