Arduino + load cell + ethernet, using REST API
- Weight measure
- Web server request
- Rest API
- Somewhat precise weight measurement
- Webserver uses HTTP 1.1 protocol
- Refreshes every 0.5 seconds
- FULL calibration (at calibration time, I lacked a WELL known weight)
- REST API
It's possible that long time use can affect the measurement, further research is required.
It's also possible to make a fancy function to re-Tare once in a while
