The Most Important Sensors in an HVAC Unit

Indoor environments have become more efficient and comfortable because of the invention of HVAC (Heating, Ventilation and Air Conditioning) systems. These HVAC systems have improved every lifestyle because:

  • It enhances comfort – It is energy saving. Whatever season you may be facing, whether the winter season or the hot season or the humid season, your HVAC system balances the right temperature inside your house according to your preferences.
  • It improves indoor air quality – It uses an air filter that that removes a wide variety of particles that might cause you harm. A good HVAC system has a quality cooling system that regulates the humidity inside your home, which helps improve the air you breathe.
  • It reduces the risk of illness – A well maintained HVAC system removes pathogens that can easily spread and affect your family.

The Important Sensors in an HVAC Unit

An HVAC unit has so many components that the human eye cannot see, just like how your HVAC systems are hidden away in your basements or attics. And even more invisible are the sensors that make every unit run smoothly. Sensors are very important parts in an HVAC system as they keep equipment running smoothly and safely, as well as to improve energy efficiency, and to preserve human health.

  • Thermostat – It is the most common sensor in an HVAC unit. Also known as an air conditioning sensor, a thermostat sensor is designed to measure the temperature inside the house. Nowadays, thermostats are digital, and use semi-conductor devices such as thermistors or resistance temperature detectors.
  • Pressure sensors – It makes an HVAC more efficient by measuring air flow and pressure throughout the system for effective air distribution. By measuring pressure and monitoring the air flow, these pressure sensors assist the HVAC system to optimize your house’s cooling, heating and air flow, reducing energy consumption.
  • Duct smoke detectors – It detects the presence of smoke in the airstream. It is essential in preventing injuries and property damages.
  • Occupancy sensors – It lets the automation system of an HVAC unit know whether or not there are people inside the room. It counts occupants and adjust the air accordingly to the needs.
  • Humidity sensors – It measures the amount of moisture in the air. The HVAC system, with the data delivered by the humidity and temperature sensor altogether, calculates the dew point temperature of the air. Humidity sensors work by detecting changes that alter electrical currents or temperature in the air.
