MAX30001 is a single-lead ECG monitoring IC which has built-in R-R detection and several other features that make it perfect for a wearable single-lead ECG application.
Several new features on this chip make it ideal for wearable applications. First is the low power consumption - just 85 uW of power and can work from 1.1 V onwards ! Also of interest is the fact that it can work with only two chest electrodes without the need for a third right-leg drive (DRL) electrode.
The best feature of this chip though is the built-in R-R detection algorithm which can measure the time between successive peaks of the QRS complex of the ECG. This means that heart-computation comes right out of the box without any microcontroller-side code requirement. Heart-rate computation just got a lot easier !!
Connection with the Arduino board is as follows:
| MAX30001 pin label | Arduino Connection | Pin Function |
|---|---|---|
| MISO | D12 | Slave out |
| MOSI | D11 | Slave in |
| SCK | D13 | Serial clock |
| CS0 | D7 | Slave select |
| FCLK | NC | External clock(32KHz) |
| INT1 | D2 | Interrupt |
| INT2 | NC | Interrupt |
| Vcc | +5V | Power Supply |
| GND | GND | GND |
