This miniature infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, micro machine workout and superior circuit design.
NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.
Why we need it.
Carbon dioxide monitors are a good way to monitor constantly busy rooms and can help in increasing air ventilation to reduce the impacts of COVID-19. It is also vital to monitor CO2 levels to ensure compliance to government notice BB101.
