| Outline of Final Research Achievements |
In this study, we have aimed to develop a small, portable, inexpensive and easy to handle PM2.5 sensing system. The system is composed of a temperature-driven Knudsen pump, and the concentration of particles is measured by the CAMM technique from the pressure difference between up- and downstream of a porous membrane. By using multiple membranes of different porous radius, it is indicated that the pressure difference and flow rate is improved. However, further improvement is required to capture particles on a membrane by using the Knudsen pump.
