ESP32 sensor node
The ESP32 sensor node collects temperature, humidity and ambient-light readings from the workbench.
The useful part of the experiment is understanding the entire path: voltage at the sensor, conversion in the microcontroller, transport over the local network and presentation without a cloud service.
Current questions:
- how much filtering belongs on the device;
- how to preserve useful readings during network interruptions;
- how little interface is necessary to understand what the room is doing.
