“Useful device. I'm trying to use it as an EMG-proxy (muscle signal) sensor as in https://www.sciencedirect.com/science/article/pii/S240589631932631X. There are lots of other uses for it too.”
“Good quality, smaller than i expected. The heart rate sensor works well, but to get good results you need to not move the finger and apply a little pressure to it with the finger, like explained in the details of the article in the store. I haven't already tried other sensors”
“Example prog worked after sorting out Python and smbus. Also had to sort out OLED display libraries. Example prog then worked fine. Sensor has difficulty in reading heart rate. Mine was 44 BPM :) It does say not for medical use.”
