Anotter USB temperature logger that can record up to four channels with thermocouple or NTCs connected via CDC directly or SCPI to USB. You can choose how you want to receive the data by moving the selector switch next to the Type-C receptacle. If you switch to CSV, it will simply output all connected channels to your console in a machine and human readable format (CSV or TSV, I prefer TSV) at about 10 readings per second. If you switch to SCPI, an SCPI terminal is displayed via USB so that you can integrate the logger into your lab equipment. This is particularly handy because you can also use it to control the OC- or H-Bridge outputs, which turns the logger into a thermal IO card. This can be useful when working with Peltier- and heating elements.

Having needed a temperature logger several times in the past, after hacking two together for spontaneous testing, I decided to develop a proper one. This is my result. :3

Inputs

Each of the four inputs can either be configured as thermocouple or NTC (resistance measuring) input. At the moment they are assembly options, I need to test if I can assmble both at the same time.

thermocouple

One MAX31855KASA can be populated per channel, enabling the reading of K-type thermocouples. Other versions of this IC are available if other thermocouple types are required.

NTC

The NTC amplifier is based on this appnote and allows amplification of small ranges to the full ADC range. This was an important motivation for this project as I needed a multi-channel body temperature logger.

If you want to know more, you can check out the schematic.

TODO

  • implement SCPI - done in the SCPI branch, check it out, but there is not much space left on the STM32, hence no merge yet
  • add sigrok communication/protocol

    DRC failures: unconnected GND pin and different pin for NTC_BOARD net

    First of all, thanks for sharing this project. I have had a similar need of logging a couple of thermocouple channels, but so far, not enough of a need to design something like this myself.

    When reviewing the board before ordering it I noticed a couple of DRC violations- most of them are harmless, but two did catch my attention:

    1. Pin 35 of U3 (GND) is not connected- probably a later routing change made it an island.
    2. Net NTC_BOARD is connected to pin 29 of U3 in PCB layout, but in schematic it's connected to pin 18.

    I'd submit a PR for item #1, but I also squeezed the width of the board a bit to get below 100mm threshold, so that JLCPCB doesn't apply large board engineering fee.
