General Description
The Hanvon N1 sensor by Hanvon Technology is a handheld device that provides real-time measurements of PM2.5 and formaldehyde (HCHO).
Principle of Operation
Hanvon N1 uses integrated laser light-scattering to measure particles smaller than 2.5 micrometers in aerodynamic diameter. It converts the signal to a PM2.5 mass concentration, sends the data to a server via WiFi and displays the readings both on the sensor screen and on a cell phone application.
