ABSTRACT
In this paper, we introduce the development of ultra-small, low power, realtime fine particles sensor. The light scattering method was applied to enable measurement device to quickly measure fine particles and it ensures mobility, low cost, convenience. Sensors for measuring fine particle detect hot spots that inhale air into the dust measuring sensor, light emitting parts that detect laser light at the sensing location, and light that divert light from the sensing station into the electric signal. Developed fine particles measurement sensor has a semi-operative optical measurement system that reduces maintenance costs and enables repeated measurement with fewer residual debris. It is also designed to provide unmanned management, providing good maintenance and consume less power than traditional commercial products.
