Micro Dust Detection System Based on Multi Particle Detector and Data Transfer to Server System

LED or LD are commonly used for personal or portable micro dust detectors. Photon scattering method is measuring the change of pulse thickness in certain time interval and convert to the particle size and numbers of particles. The advantage of applying photon scattering method is the real time measurement. However, while converting the numbers of scattered photons, accuracy is sacrificed. Especially, for very small micro dust this issue will lead to critical uncertainty. Five different output signals were used to compare and develop accurate system. The efficient software method to transfer data to server is discussed as well.
