Living Observatory Sensor Network

On Saturday, I installed a PurpleAir Flex Air Quality Monitor at the Tidmarsh Headwaters North location. The sensor measures PM2.5 concentration along with pressure, temperature, and humidity. You can view the Air Quality Index (AQI) data from the sensor on the PurpleAir map.

To begin at the beginning,

The Central Stream Cam at Tidmarsh, which normally streams 24/7 live video that you can view by clicking here, stopped responding on November 20th. The last video it recorded didn't provide any clues, as it just shows ducks swimming by. Our Southern Marsh cam also failed this fall, after working flawlessly for several years. Yesterday, I made the trip down to Tidmarsh to investigate, with Glorianna in the field with me to help and document.
