The air quality monitoring was funded via the Air Quality Monitoring Pledge Drive. All monitors report CO2 and VOC index. In a few places the monitors also have PMSA003 sensors for PM1.0, PM2.5, PM10.0. These measurements are (will be) pushed to MQTT to the topic nh/air, where they are then ingested into Prometheus for visualisation via Grafana.
Current Status
The boards are gradually being built. Steve is designing an enclosure for them. We should have a few up and running soon.

Hardware Description
The board is based around an Atmega 328p and WizNet W5500 Ethernet controller. There's a small buck supply to make powering the board more flexible. The VOC sensor used is a SGP40, and CO2 is reported with a SCD41. For boards which also measure air particles, they have a PMSA003 onboard. Out of curiosity and to help debugging, each board also has a INA219A chip and 0.1 ohm shunt. This allows the board to monitor its own power consumption.
