MerryIoT Air Quality CO2
Best-in-class integrated 3-in-1 CO2 sensor
CO2 / Temperature / Humidity
Compliance to LoRaWAN1.0.3
Integrated best-in-class 3 in 1 CO2 sensor with temperature and humidity sensor
Measurement range: 400 ppm –10000 ppm
Accuracy: ±(30 ppm + 3%)
Estimate battery lifetime: 2 years(Note: Battery life is mainly determined by the reporting frequency. Other factors include moisture and high temperature.)
IP40 equivalent
Easy operation: Simply wave in front of the device to receive a color-coded visual indicator of the overall air quality: Green (Good), Yellow (Fair), Red (Poor)
Press-and-play installation
Indoor air quality is sometimes worse than the air quality outdoors, however, we now stay indoors more than ever before! You can now define your own comfortable environment using an easily managed app and the MerryIoT Air Quality CO2 monitor! Monitor the level of carbon dioxide, temperature, as well as humidity 24/7 in real-time!
