Hello,

I'm interested in your SDI-12 adapter to connect multiple environmental sensors (turbidity, conductivity, oxygen).
My goal is to build an autonomous, battery-powered system (using either LiSOCl₂ or Li-Po batteries) with at least one month of autonomy.

I’m not sure which kind of "computer" or microcontroller would be best suited for your system, since my only requirement is to store data locally on an SD card.
Do you have any recommendations for a compact and low-power platform?
I’m considering options like the Raspberry Pi Zero or a STM32-based board, but low power consumption and small size are essential since the probe will be deployed at sea.

Also, my sensors draw brief current peaks of 500 mA for 2 ms at 12 V.
Do you think your SDI-12 adapter can handle this type of load?

Thank you in advance for your help — and for your great work.

Best regards,
Julia
