Removed from BC tower and brought back to the lab. It needs a new data card slot. The current card slot has a bad spring mechanism so cards don't physically mount. |

Bouldin Corn Air Quality Sensor |
Installed at Bouldin Corn on the southwest scaffolding post. It is powered by mini-USB-to-USB cable that connects in the dfPAR CR10X enclosure. The microSD card slot is tucked up into the inner PVC shield to prevent water from dripping on it. The card slot is easy to pull out and tuck back in when I need to access the card. |

Maintenance |
Lab none |
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. |
