Very first post on these forums so be nice :cold_sweat:
I'm attempting to build a temperature controller using a DS18B20 and a power relay. The idea is to use this in a chest freezer to keep the temperature within a set temp range by controlling when the chest freezer is turned on/off. Exact same functionality as a love/ranco controller. The extra features that I want to add to this are beyond the scope of what I'm looking for in this post, so here are the questions:
- Beyond the probe and relay, is there something I am missing that will be required? (Module, shield, etc)
- I know that I need to make sure that the power relay can handle the load of large appliances. However, almost all relays I am finding on the arduino shops are similar to this one: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=218 which only supports up to 10A. Are there any recommended relays for this particular application?
Just trying to plan this out and am definitely inexperienced, so I apologize in advance if I'm making too many assumptions or incorrect.
