Hey, everyone. It’s been a while since I’ve been on this forum and since I’ve been able to do some projects with my arduino, but I finally have a good reason to bring it out again.
I need to control the temperature of a mini fridge to be in the 60-70F range (started homebrewing beer). Right now, the lowest setting on the built in temperature control of the mini fridge is keeping it at about 44F.
I would like to set up a temperature controller with my arduino using a thermocouple or similar, and a relay to control when the refrigerator gets power.
The mini fridge I bought is an Igloo model fr320 and according to the manual, the specs say that it is rated at 115V~/60Hz/1.3A. I don’t really know what kind of relay to buy. I did some research and I found out that someone suggested this one to another guy http://www.allelectronics.com/make-a-store/item/RLY-499/5-VDC-SPDT-6A-RELAY/1.html and it was rated to handle 120V through the contacts and it should be able to be controlled by the arduino.
My main question is: Can anyone help me learn how to buy relays for my needs so that, if they stock them in a nearby electronics store, I will be able to pick one out?
I’m sorry if this seems too basic. I did try to do some research but came up short.
Thank you in advance!
