Basic temperature recording system using Netduino
I've wanted one of these for a long time, so I built one.
Overview and caveats:
- Netduino plus 2 reads up to 32 DS18B20 sensors and sends the data to a webservice
- Webservice inserts data into a local SQL database
- Designed to operate on a trusted network (for now), there's no message security, encryption, authentication currently.
- Netduino plus 2 firmware (ver 4.3.1) has a bug where trying to connect to a host that isn't responding freezes up the device (never times out). Working on isolating this seperately.
- This means a powercycle is necessary if the service goes down for any length of time.
