Moji China - AirNut

General Description

The AirNut sensor is a handheld device that provides real-time measurements of fine particles (PM_2.5), Carbon Dioxide (CO₂), temperature (C) and relative humidity (%).  

Principle of Operation

AirNut uses light-scattering to measure particles smaller than 2.5 micrometers in aerodynamic diameter. It converts the signal to a PM_2.5 mass concentration, sends the data to a server via WiFi and displays the readings on a website and a cell phone application.
