Integrated blower sensor unit for laptop

An integrated blower sensor unit, used for a laptop and mounted on a side wall or a bottom wall of a blower adjacent to an in-flow air path, and comprising:

• a unit substrate, comprising a plurality of power inputs and a plurality of communication pads disposed on a bottom side thereof to be an interface with an external microcontroller;
• a blower sensor chip, disposed on the unit substrate, electrically connected to the unit substrate with a plurality of bonding wires, and comprising:
• a silicon base, disposed on the unit substrate;
• a non-contact thermal sensor, disposed on the silicon base, and configured to sense an in-flow air temperature;
• and
• an air flow sensor, disposed on the silicon base, and comprising a cavity defined on the silicon base and a membrane disposed above the cavity;
• a signal processing element, disposed on the unit substrate, connected to the non-contact thermal sensor and the air flow sensor, and configured to perform an analog signal processing and/or an analog to digital conversion with a serial communication interface;
• and
• a cover cap, disposed on the unit substrate, and comprising two holes defined along the in-flow air path.
