HKT Indoor Air Quality Sensor: Reassuring Indoor Ambience Monitoring

Monitoring indoor air quality is integral to public health and well-being and is directly linked to respiratory diseases and cognitive performance. According to a Harvard study, cognitive scores were 61% higher in office environments with enhanced ventilation, underscoring the necessity of precise indoor air quality management. [1] At the same time, HKT Indoor Air Quality Sensor provides a state-of-the-art solution to monitor critical quality parameters, including but not limited to particulate matter, volatile organic compounds, carbon dioxide, and temperature and humidity.

In schools, it supports improved cognitive function, mitigates the spread of airborne pathogens, and fosters a healthier learning environment. In hospitals, it aids in controlling infection rates and maintaining strict climate controls for patient recovery. Moreover, it enhances occupant comfort, reduces sick building syndrome, and can drive energy efficiency by smartly regulating HVAC systems for office and apartment buildings. Hotels can leverage HKT to provide a superior guest experience while emphasizing health and comfort, ultimately boosting revenue.


How HKT Indoor Air Quality Sensor Works

Our indoor air quality sensor operates synergistically and integrates multiple sophisticated detection technologies.


  • For dust particle concentration, the sensor deploys a Laser Scattering method, wherein a laser diode irradiates dust particles (PM 2.5/PM 10), causing them to scatter light detected by a photodiode to calculate particle concentration.
  • Motion detection is achieved using a passive infrared (PIR) sensor, which identifies changes in infrared radiation from moving objects.
  • The device incorporates non-dispersive infrared (NDIR) sensors for CO2 and electrochemical sensors for HCHO/O3 to detect harmful gases. They measure the absorption of IR or changes in electrochemical activity to gauge gas concentrations.

  • When measuring light, a photodiode is used because it changes the amount of light that strikes it into a current proportionate to the amount of light.
  • Finally, the device employs a digital barometric pressure and temperature and humidity sensor for ambient environmental measurements, which uses thermistors, capacitive humidity sensing, and piezoresistive pressure sensing technologies.
