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.

Thanks to the Southeastern Massachusetts Pine Barrens Alliance (SEMPBA) for providing the sensor, which was funded through a Massachusetts DEP grant.
