Sensor data acquisition system for smartphone

摘要

The present invention relates to a sensor data acquisition device for a smartphone, which converts an analog signal outputted from various sensor circuits into a digital signal and stores the digital signal in a storage device of a smartphone. The sensor data acquisition device for a smartphone according to the present invention receives a DC voltage from a smartphone and implements most of circuits in one semiconductor integrated circuit chip by applying a digital logic synthesis method without an additional power supply, thereby minimizing an analog circuit.
