Title: Maintenance
Notes: This sensor had some corrosion on one of the power connectors inside the sensor (it got rained on after the BC tower fell over), so Joe bypassed it by attaching one long mini-USB-to-USB cable. The clock was also ahead by one day. I brought the sensor home to connect to my home wifi for a few hours for the clock to automatically sync with the network. I checked the data files on the card and the timestamps were good.
