Particle PM2.5 User manual

1 - Description
This device is an air quality detector included several measures, intel-
ligent induction, and cloud data storage. It can detect PM2.5, PM10,
CO2, HCHO, TVOC, temperature and humidity. This device uses laser
scattering weight test method, with professional structure design,
professional fan, and original particle. It can sensitively and precisely
detect and monitor PM2.5 and PM10, helping you know your indoor
air quality. It uses professional CO2 Sensor, can remind you to open
windows when indoor concentration of CO2 is too high. HCHO can
detect formaldehyde and TVOC can detect indoor harmful gas, help
you know environmental pollution. In order to detect PM2.5, PM10,
CO2, HCHO, TVOC at the same time, it adopts reliable power supply
circuit to ensure all measures are precise and stable and work time is
as long as possible. This device adds rich experience of intelligence.
Wi-Fi module is optional. With cloud data storage, mobile phone you
can have a remote view of real-time data and access device controls.
Noise detection module is equipped. You can awaken device to start
measure by generate a slight noise when device is sleeping.
