Arduino based sensor learning project. This project is further application from Health_Sensor_ecg_ppg_max86150 dev-board, plotting the ECG curve which used Processing on your computer.
-
Bias Cancellation | Store raw data in time, when new data coming that bias level will calculate as hysteresis filter.
-
Heart Rate Detect | Check windows will output the BPM results (ECG).
This board also support WiFi transmission via ESPNOW (ESP8266 Broadcast), and need power by battery. You need 2x esp8266 board.
- Read receiver esp8266's mac address.
- Fill it into the transmitter sketch. "ECG_ESP8266_MAX86150_V6"
** A Known Issue **
Sampling rate from MAX86150 set as 200sps, but ESP8266's multiplex with ESP-NOW and sensor hub reading task will low down the output sample rate to ~150sps. When you measuring your ECG in real-time plot may show the missing R-R interval. (R-peak missing!) Don't worry, it just the lower sample caused.
Arduino tool kit, and require the following material:
- MCU: ESP8266
- Sensor: MAX86150
For coding example, you need the following library:
