Hello, sorry for my bad English and for me hard to find information on the forum. I have a good idea, but for it I need pulse sensor which can work on the wrist, I found this (SEN42758M) seeedstudio.com/wiki/Piezoel … lse_sensor
is it work on wrist ? and can i connect it to different microcontrollers ?
yes, sure i can works on wrist!
the output is some pulse, just connect it to the IO/analog of any microcontrollers, it’ll works fine ~ besides, if your mcu hasn’t a analogIO, you can connect it into a comparator .
