EM500-CO₂ Carbon Dioxide Sensor


EM500-CO₂ Carbon Dioxide Sensor (4 in 1)


CO2 Sensor (4 in 1)

EM500-CO2 is designed for measuring gaseous carbon dioxide (CO2) concentration in harsh environments. It is useful in the application where knowing CO2 level is important like greenhouse, building ventilation, fruit and vegetable storage. Besides, it also supports temperature, humidity and barometric pressure measurement.

  • Measuring ranges from 400ppm to 5000ppm
  • Easy installation in any enclosed areas or outdoors
  • 4 in 1 (CO2, barometric pressure, humidity, temperature)


Smart Wine Cellar >>>
Carbon dioxide is a by-product produced during the fermentation of wine. Because the density of carbon dioxide is heavier than air, it is easy to overflow from the fermentation tank. When it falls on the ground of the winery, it will form fatal and undetectable potholes, which will bring great hidden danger to the safety of the operators.


Forest Fire Detection >>>

Nowadays, forest fires often cause serious threats to the environment and produce real emergency situations and natural disasters. Most of the times, when someone notices about the fire, it is too late because the fire has spread already. Thus, the enhancement of forest fire detection system by CO2 (carbon dioxide) monitoring can be evaluated.



Cloud Web & APP:

CO2 Sensor works perfectly with Milesight IoT Cloud (Web & App), which allows you to monitor your data in the office or on the go. With a drag-and-drop experience, Milesight IoT Cloud provides rich features such as intuitive widgets, triggers, sharing and transfer ownership of devices, layers, etc.
