I want to control a few water pumps (low power, aquarium kind of<br>
pumps) via software, and read inputs from a sensor or two (humidity,<br>
temperature).<br>
<br>
I'd like a solution that is cheap, I can bring up as quickly as<br>
possible with as little work as possible, ideally no to little<br>
soldering, I can easily program with good libraries (python / C /<br>
whatever is fine). Eg, I'd like this to be a one afternoon project, I<br>
plan to get most of my hacking fun by playing with the result, rather<br>
than with building the system :)<br>
<br>
I was looking into:<br>
1) raspberry PI + relay board + sensors.<br>
2) Arduino + relay board + sensors - seems like a bit more work than<br>
the above? even if more flexible?<br>
3) Something like:<br>

they seem to have tons of pre-made relatively low effort solutions.<br>
<br>
I've had some embedded experience in the past, but have not used any<br>
of the above. Suggestions? hints? experiences?<br>
<br>
Thanks!<br>
