HVAC (heating, ventilation, and air conditioning) controls and sensors are devices used to regulate the temperature and air quality of indoor spaces. They are used in a variety of settings including residential, commercial, and industrial buildings. HVAC controls and sensors work together to provide a comfortable and safe environment for occupants. The main components of HVAC systems are the thermostat, which measures and regulates the temperature, and the air handler, which is responsible for circulating and conditioning the air. HVAC controls and sensors are also used to monitor humidity levels and to adjust fan speeds in order to maintain the desired comfort level. HVAC controls and sensors can be manual or automated. Manual controls are typically operated by a thermostat, while automated controls are operated by a computer or other intelligent device. Automated controls can be used to program temperature levels and set times for the system to turn on or off. In addition to temperature and air quality, HVAC controls and sensors are also used to monitor energy consumption. This is done by measuring the amount of electricity used by the system and adjusting the fan speed accordingly. This can help to reduce energy costs by ensuring that the system is only running at the necessary level.
