MAXREFDES101 can measure the PPG signal and hence is capable of measuring Sp02 by using two LEDs of different wavelengths (typically Red and IR). This requires modification of the sensor board. However…
Yes, the MAXREFDES101 can be used to extract respiratory rate. MAXREFDES101 has both ECG and PPG sensing capabilities built into it and both signals can be used to measure the respiration rate.
Hence…
The wrist strap used in MAXREFDES101 is a generic 22 mm quick release wrist strap but it can be any 22 mm quick release.
We used this on our HSP2.0:

Q:
I turned on the MAXREFDES101# watch (green LED is flashing) but it is not found when I start the Android HSP-App
A:
- Leave the HSP app (tapping return)
- Turn off Bluetooth within your phone…
If the customer cannot turn the watch off with a short press of the power button, and the watch display is frozen or the microcontroller has locked up, a long press of >12 seconds will power down the watch…
