Hanvon-N1

General Description

The Hanvon N1 sensor by Hanvon Technology is a handheld device that provides real-time measurements of PM_2.5 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 PM_2.5 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.
