Abstract :
A hardware proposal of wireless oxygen saturation detection device has been designed in this paper based on ARM. The proposal applied ARM process as the main control unit which simulates oxygen saturation characteristic signal extraction and detects oxygen saturation data by amplification circuits according to the Lambert-Beer law. With low-cost, high-accuracy and wireless transmission characteristics, a RF24L01 module was connected to the main control unit though SPI interface to realize wireless detected-data transmission. The design which suits for clinical observation and teleconsultation would have good application value and the market prospect obviously.
