EnviroTron
EnviroTron is a small sensor board that measures the world around it. Temperature, humidity, pressure, light, sound, and motion are all recorded and uploaded (via Wifi) to a central InfluxDB database. Grafana is then used to display the collected data and provide notifications and alarms based on desired criteria.
These sensors are part of a larger home automation project, called “marvin”, that includes feedback and control of other appliances and systems.
