Portable Non invasive Device for Measuring the
Peripheral Oxygenation Level (Part B)
The device include a reflectance sensor by Nellocr, a tran
impedance circuit and filters, for the processing unit an
Arduino Uno was chosen:
Photodiode
Artery
Vein
Red and
Infra-Red
LEDs
Tran-

sensor
•
An indicator circuit was built using green, yellow
and red LEDs to implement the traffic light idea.
•
An android application was developed to receive
oxygen level wirelessly via Bluetooth.
Since the measurement location is the
forehead, a wireless communication is needed
so that the result will be displayed on a
comfortable location.
Result
•
A prototype of the desirable device was developed and
compared with existing measurement methods.
Conclusions
• The prototype is proven to be reliable and
sensitive for changes in the oxygenation levels
and allows monitoring of the local peripheral
vasomotion changes.
• The android application has a potential to improve
the medical care.
• In summary, this innovative device has a potential
to improve home care for patients suffer from
respiratory diseases who need frequent
measurements of oxygen saturation during
wakefulness and sleep.
