Abstract: A semiconductor-based multi-sensor module integrates miniature temperature, pressure, and humidity sensors onto a single substrate. Pressure and humidity sensors can be implemented as capacitive thin film sensors, while the temperature sensor is implemented as a precision miniature Wheatstone bridge. Such multi-sensor modules can be used as building blocks in application-specific integrated circuits (ASICs). Furthermore, the multi-sensor module can be built on top of existing circuitry that can be used to process signals from the sensors. An integrated multi-sensor module that uses differential sensors can measure a variety of localized ambient environmental conditions substantially simultaneously, and with a high level of precision. The multi-sensor module also features an integrated heater that can be used to calibrate or to adjust the sensors, either automatically or as needed. Such a miniature integrated multi-sensor module that features low power consumption can be used in medical monitoring and mobile computing, including smart phone applications.
