Audited Supplier LoRa wireless CO2 RH and Temperature monitor controls the ventilation devices, Indoor Air Quality Monitor CO2 with NDIR Sensor
In the face of a global pandemic, such as that caused by the SARS- -CoV -2 virus, the prevention of new infections is essential to stop the spread and ultimately return to normality. In addition to wearing masks and maintaining safe distances, regular ventilation in enclosed spaces where several people are gathered has proven to be an effective protective measure as advised by the World Health Organization.
Additionally, as has been shown in a recent study of other airborne viruses, there is a strong correlation between the CO2 level and aerosol content in a confined space under the assumption humans are the only CO2 source. This can be exploited by means of a low-cost infrared CO2 sensor to indirectly monitor the aerosol content and to provide targeted ventilation if predefined thresholds are exceeded.
The distributed CO2 monitoring network presented in this paper extends that idea and provides an inexpensive, comprehensive and modular monitoring network based on readily available components and 3D printing. By using a long-range communication link (LoRa) to centrally collect the real-time CO2concentration in a multitude of rooms, this network is particularly suitable for larger building complexes such as kindergartens, schools and universities without requiring partial or even full WLAN coverage.
Product description
This product SA1300C indoor air quality monitor is a Large LCD desktop and wall mountable instrument that measures CO2 concentration in air.
The co2 monitor displays real-time value of CO2 concentration,temperature and relative humidity.
1.The measured CO2 value in ppm(parts-per-million)will be displayed on the LCD with tee states indication:Good(0 to 800ppm),Normal(800 to 1200ppm),Poor(>1200ppm).Programmable alarm setting by users
3.Powered by USB,or optional AC adapter.or plug
4.CE certificate
