MakePython ESP32 is a powerful, generic Wifi+ BLE MCU module target to MicroPython learners & developers. It is true “breadboard compatible”, with the very detailed pins explanation, it is easy to learn& use. The MakePython ESP32 has 2 optional for users: WROOM(NO PSRAM) and WROVER(8MB PSRAM).
Overview: ESP32 MAX30100 WebServer
In this project, you will learn to make ESP32 based MAX30100 Pulse Oximeter Webserver. Our previous project was based on ESP8266 NodeMCU where we monitor the BPM and Sp02 parameters of the oximeter sensors in the webserver. But in today’s project, we will monitor Heart Rate and oxygen saturation (Sp02) values on the ESP32 Webserver. You can monitor those values from any smartphone or PC which has wifi support and browsing capabilities.
In today’s tutorial, you will learn to:
- Interface the MAX30100 Pulse Oximeter sensor with ESP32.
- Program ESP32 board using Arduino IDE.
- Create a beautiful ESP32 local webserver to display BPM and Sp02 parameters.
Components Required
To make an ESP32 based MAX30100 Pulse Oximeter Webserver, you will need the ESP32 Development board. A MAX30100 Pulse oximeter sensor, few jumper cables, and a breadboard. You can buy all these components from the Amazon link provided below.
Interfacing MAX30100 with ESP8266 NodeMCU
The Circuit assembly for MAX30100 Pulse Oximeter Webserver using ESP32 is very simple. The MAX30100 Oximeter Sensor works with the I2C bus. So, Interface the I2C pins (SCL &SDA) oximeter modules with GPIO 22 and GPIO 22 pins of ESP32. Connect the INT pin to the NodeMCU GPIO 19 pin. Similarly, provide 3.3V power to the VCC and Ground the GND pin. Basically, you can follow the circuit diagram to make your connections.
