ESP8266 Heart Monitor with ECG style graphic

Materials needed

• ESP8266 board
• AD8232 - the one I used can be found here
• ECG electrode pads - example here

Configuration

Connect the ECG module to ground, 5v, and analog pin on ESP8266. Be sure to open the sketch file (heart_monitor.ino) and input your WiFi settings.

Run the client WPF application. The ESP8266 will detect there is no client connected, and will broadcast a packet over UDP. The desktop client will see this UDP broadcast, and automatically connect. Takes up to 3 seconds. Once connection has been made, you should begin seeing the graph running.

ECG Placement

• Important note: wearing a shirt will cause massive interference from the static electricity
• I have found the Fontaine placement method works best.

If you purchased the DFRobot module I did, then here is the color guide:

• RA: Red
• LA: Green
• LL: Yellow
