A summary of DIY blood oximeters. It is really rewarding to read it. [Copy link]

 

The oximeter is a common portable medical electronic product. It is not big in size and has few functions, so it is not difficult to develop. However, although it is small, it has all the necessary functions. The oximeter is a complete small system. Many netizens have DIYed oximeters and recorded their development process in the EE forum. Today, Xiaoguan reviewed the experience posts posted by netizens before and felt that it was very rewarding. I might as well go all out and spend some time to organize it. Friends who see this post, if you think Xiaoguan’s work today is still valuable, please reply to encourage me. If you feel that I haven’t hit the point or said the key content, you are more welcome to reply to supplement it. Of course, if you are willing to open a separate post and share your valuable information in the forum with everyone, Xiaoguan will be very grateful.

Without further ado, here are some highlights from previous issues compiled by Xiaoguan:

Yes, if infected, the lungs will be affected, resulting in insufficient oxygen supply to the human body, and the manifestation parameter is blood oxygen saturation.
