Pin-Configuration of the ECG-Chip AD8232

[cleeee]

Hi,

I read the datasheet of the ECG-Chip AD8232, because I want to build a ECG by connecting the AD8232 board to the arduino. I wonder which funktionality the pins LO+ LO- and SD have, because I could not find it in the data sheet. Can anybody help me?
Here is also a link to the homepage:

Hi Tom,

thanks, I had already this information. But my point is, what is the function of LO-, LO+ and SDN?

Hi,

@cleeee

But my point is, what is the function of LO-, LO+ and SDN?

If you read the code in the site I posted.
LO- and LO+ are outputs from the module to indicate if either or both sensors have fallen off, a very important thing to know.
SND is the SHUTDOWN pin, leave it open and the module will operate, pull it HIGH and you shutdown or disable the module.
