This is the platform to collect all kind of indoor environment quality (IEQ) real-time data input with wide range of sensors (e.g. PM2.5, TVOC, CO2, temperature, humidity and human-body surfaces’ temperature) and big data (e.g. local weather data and PM2.5 data). With the collected data, the platform is developed to orchestrate the control of humanised circadian lighting, air purifier and air-conditioning so as to provide the best mixture of control sequences.
