- Low Power EKG & Heart Rate Monitor using the MSP430FG439
This design details how to build a digital heart-rate monitor using a MSP430FG439 microcontroller (MCU). The heartbeat rate per minute is displayed on an LCD and generates a digital data stream via an RS232 serial port to allow EKG waveform display on a PC. The entire application runs using a CR2032 3-V lithium battery.
This reference design details non-invasive optical plethysmography – pulsoximetry – using the MSP430FG437 microcontroller (MCU). The pulsoximeter consists of a peripheral probe combined with the MCU displaying the oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both heart-rate detection and pulsoximetering in this application. A custom LabVIEW GUI has been developed for this application to display the heart signal, heart rate and % SaO2 number. All the necessary files and steps to get this GUI up and running have been provided along with this report.
This design, featuring the ultra-low-power MSP430 MCU paired with a TMS37157 Passive Low Frequency RFID device can enable a ultra-low power wireless temperature & humidity sensor (SHT21). With RFID, applications can benefit from hermetically sealed enclosures by leveraging RFID to provide power and data transmission wirelessly through an enclosure. This design provides complete hardware, software & PC-side software to get you up and running.
