DIY Pulse Oximeter

at 5:41 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks, Insane Equipment


DIY medical equipment is not a big hobby area but this DIY Pulse Oximeter is one cool device. I have no idea what a commercial Pulse Oximeter but like anything medical the real stuff that is used in hospitals usually costs big bucks. In this case your finger is slipped between two pieces of medical grade oak to take the reading.  The project is based around the powerful 68HC908AB32 microcontroller.

Thanks Maciek

“A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patient’s blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmograph. It is often attached to a medical monitor so staff can see a patient’s oxygenation at all times.”

    Have you not read the disclaimer on the last page of the data sheet? your not allowed to use the 68HC908AB32 in medical equipment, so if you die then its your own fault lol.

    Chris, this would be an astute observation making you seem smarter than you actually are if this device had any medical complication possibilities. One reason this device would never be classified as a Class III medical device because the grounds are completely isolated from the human body. Medical devices that directly attach some conductive material to the body would be a non-isolated ground unless they used some form of induction or RF signals. This devices uses light variances; completely isolated. All that being said, you ARE allowed to use this microcontroller, mainly because it’s not a device that is going to be used in a medical environment.
