Sensors are integral to most heating, ventilation, air-conditioning and refrigeration (HVACR) systems. As HVAC systems have had to become far more efficient, there has been a comparable need and push for much finer control of the various subsystems. This has led to advances such as variable refrigerant flow, variable speed motors and blowers, electronic expansion valves, and many other control methodologies to finely tune the system and minimize the overall energy use.
