I'm looking to use an Arduino board to control power output based on ambient temps inside a case.
The fan (one or two) are 0.18A 12V.
I have the following Arduino boards:
I have a Power Supply for the Fans and Arduino will be this 24V unit.
I have these temp/humidity sensors.
I have 5V DC relays to 125v 5A and 10A.
I think I'm going to need something to convert the 24V DC output to the input current for one of the Arduino's above ... suggestions? The Uno operates on 7V to 12V DC 1-2A I think?
I'm not sure what Arduino board to use from the list above (guessing Uno), suggestions?
The basic purpose of the circuit is to increase output to the fans as the temps increase. Now I realize there are probably fan controllers that might be able to do this for me, but I want to have my own circuit (that I may update later to include temps display and power curve adjustments and humidity adjustments).
