Air quality monitor/For CO2, temperature and humidity (Non-dispersive infrared absorption- NDIR)

Description

Temperature and relative humidity

The apparent temperature depends on several factors, such as air temperature, thermal radiation, relative humidity, wind speed, human activity and health status, clothing, etc. Among them, air quality monitor for co2  temperature and relative humidity are two important factors affecting human comfort. We generally feel comfortable at the temperature of 20 °C to 24 °C and a RH of 30% to 60% in winter and at the temperature of 23 °C to 26 °C and a RH of 25% to 60% in summer.
