Oximeter with IoTy
This sensor measures oxigenation as Sp02 , temperature, and Heart Rate.
In the IoTy example you can can connect this and an OLED to ESP32, and write the following code:
Wiring:
VIN to 3V3
GND to Gnd
SCL to SCL
SDA to SDA
SCL & SDA are clock and data lines for I2C communication between electronics.
In the code above you will see we define 2 unique I2C buses – one for the Oximeter, anc one for the OLED.
You will need to Load 2 IoTy Extensions: MAX30102 and SSD-1306
We connected MAX30102 SCL/SDA to D18/D19.
We connected SSD-1306 (OLED) SCL/SDA to D25/D26.
