As per my application described in my earlier question, can someone please suggest whether I should power a remote circuit (placed inside a water tank on a terrace):

  • with a battery (AA/AAA batteries or Li-Battery or any other one, along with optional small solar panel for charging the battery)

or

  • using DC power lines that will be supplied from my home (5-10 m away from the remote circuit).

The remote circuit will most probably be working at 5 VDC with max current consumption of 500 mA.

I want to decide the same on the basis of involved complexity and cost of the above solutions that will be worth it for my requirements. Any other/new suggestion is welcomed.

    The answer posted for your original question clearly states that it is simple to use the cable for both power and signal. – DrMoishe Pippik Sep 30 '20 at 04:17

    Maneesh, you're posting a lot of questions, asking slightly different aspects of the same question for the same project. That leads to a lot of repeated effort for us on all these same-but-a-little-different questions. The site is not a project discussion forum for you to try out all sorts of possibilities and is not be used as one. Please write one single question that states all - all - of your existing thinking, reasons and findings. Please don't post more 'what about this idea then?' questions where the answerers are expected to do all of the thinking. It's not a personal tutorial site. – TonyM Sep 30 '20 at 13:30
  • @TonyM I apologize for the inconvenience caused. – Maneesh Verma Oct 01 '20 at 11:22
  • Apology accepted, thank you. Take the tour, see how the site works, think through your questions and consolidate them into fewer, well-written ones. Turn this into a positive and make some progress :-) – TonyM Oct 01 '20 at 12:23

with AA Batteries at 500mA you only can expect 3-6 hours of lifetime...

"with max current consumption of 500mA"

is a bit vague, but to me it indicates, you need another power source concept or a measurement system which is more energy efficient
