I am looking to use arduino to monitor scalp oximetry and scalp temperature. I am also interested in adding a microphone and photo-resistor as addtional inputs too. I want to be able to send the data via bluetooth.
I am new to ardunio, I was wondering what product would be best for this project?
Are you sure that you want to measure hair temperature? I use an oximeter for fingers, maybe suitable for ears as well. Dunno which sensor is inside, though.
Hair was not mentioned by the OP.
The persons of interest to him generally have minimal or no hair.
Almost all surface oximeters use dual colour LED and photo-diode sensors. A clever trick is to connect the LEDs back-to-back, sharing two wires.
