MAKE THE SMART ROOM AIR CONDITIONER CONTROLLER

摘要

This PICAXE project was originally designed to control a room A/C for use in an inexpensive walk-in cooler. However, this is just one of the duties this smart gadget is capable of. Most practical ideas come from a real-life problem that needs to be solved. The problem that inspired this project was the need for a walk-in cooler that I could afford, which could be kept at the temperature of an average fridge (38°F to 40°F). I already had an old room A/C and thought there was a possibility I could use it as the refrigeration unit. The problems in using an inexpensive room A/C are legion and, at first look, a bit frightening.
