【Abstract】 Integrated sensor has the advantages of less weight, small size , low cost and high reliability. A design of integrated sensors for measuring humidity, temperature and pressure were described in the paper. Considering compatibility of MEMS processing, thermal conductivity method was used to measure humidity, and Pt resistance used to measure temperature, and capacitive sensor to measure pressure. The characteristics of the sensor have been calculated and simulated. The design and fabrication processing was introduced.更多还原
