I need one project Single Pulse Oximeter. I need the schematic, code program and one prototype. The project need to work in low perfusion, 0,075% of perfusion is necessary and 0,05% of perfusion is very good. The sensor need to be analog. The project need to calcule the pulse rate and the SpO2 sapturation and need to send this data to UART. The microcontoler can be MSP430 or ARM (lpc family of NXP). I need this project as soon as possible.
