Millikelvin Temperature Monitor
-------------------------------
Because we are fighting a lot of drift issues with the STM, we assume that
temperature deviations have a catastrophic effect on the system. To gain some
insights, we built a little temperature minitor for correlating the STM drift
to temperature fluctuations.
### Hardware
The following components were used:
- A cheap `MF52D 3950K` 10k NTC thermistor
- An ADC breakout board based on the CS1237 chip ([Breakout Board Docs](https://github.com/yasir-shahzad/CS1237-24-Bit-ADC-Module))
- A Raspberry Pi Pico 2

### Software
On the Pico 2, a small micropython script is running. To deploy the code, you
need [`mpremote`](https://docs.micropython.org/en/latest/reference/mpremote.html):
```bash
mpremote cp cs1237.py :
mpremote cp temperature_monitor.py :
mpremote cp main.py :
```
Replug the Pico USB cable and data should be sent in over serial.
To monitor, we are currently using the [`serial-monitor-rust`](https://github.com/hacknus/serial-monitor-rust) tool.
