Looking for help choosing a data logger board

Post by HansH »

Hi,

I'm looking around for components for stand alone temperature logging at low energy requirement.
- I already chose Adafruit PT1000RTD (Id.3648) to evaluate a PT1000 sensor with 4 wire measurement.

Now I'm searching for board to take the measurements from this PT1000 board, combine them with real-time data and store them.
It should have the requirements
  • memory capacity to store a few ten-thousend data sets (or more)
  • low energy, capable to work with a (LiPo?) battery for a few months stand alone
  • reliably working deep sleep mode
  • dimension as small as possible, i.e. not much more short dimension than 25mm, while its length is less important.
  • real time clock
  • there is no need for real time data transmission through the air
  • reliability (no unexpetected stop or data loss)
As a beginning I came across with the boards
  • Adafruits Feather product line, i.e. the HUZZAH board (Id 2821)
  • Adafruits Trinket product line M0 (Id 3500)
  • Arduino Nano
  • WEMOS D1 mini lite (consumes only 0,04mA in sleep mode)
  • Teensy 4.1 ((Mb Flash)
  • some boards with the option to write to SD-cards instead of Flash
  • and I guess there might be much more or better suitable boards.
It would be helpful to get some guidance and help, to sort out, what might be usable for my project.
Often I do not find, power consumption information. Sometimes I have problems to figure out, if there might be icompatibilities, as I'm not too experienced in that are. So I don't know the special points where to look first.

Thanks
Hans
