Knowledge on ECG using python..

The main goal of unobtrusive sensing is to enable continuous monitoring of the human body's physical activities and behaviours as well as during the subject's daily activities. The measured vital signs include body temperature, ECG and oxygen saturation (SpO2). I'm using a TMP36 for the temperature sensor and I've done the code in Python, which is to be used on a Raspberry Pi 3. An MCP3008 ADC is being used to convert circuits from analog to digital to interface with the Raspberry Pi. I will need codes for SpO2 and ECG circuits.
