BIOGRAPHY
My research has focused on dew point sensor. The sensor is composed of a quartz crystal and a Peltier module. It is based on the resonant sensing principle. Proactive approach is taken to produce condensation in the surface of the quartz crystal and it will lead to a change in both electrical characteristics and oscillation frequency of the quartz crystal. Then, based on observation of such changes two main approaches are proposed to measure dew point. One way is to use the quartz resonant circuit with high sensitivity and frequency output type is applied in the second way.
