For: DIY air-quality monitor builders
Worth noticing: The page says the node averages readings every five minutes and cautions that humidity can limit the absolute accuracy of low-cost particle sensors.

Field notes

The described node uses an ESP32-C3 and replaceable sensor components, with an optional LoRa module for locations outside Wi-Fi range. Its server example uses a TOML configuration file, and the page says the project is built and maintained in spare time; the displayed version is v0.4.
