Using the olimex ecg sensor with other platforms
« on: July 11, 2019, 10:52:30 AM »
hi, i would like to use the olimex ecg sensor with esp32 Wroom.
https://www.olimex.com/Products/Duino/Shields/SHIELD-EKG-EMG/
https://www.olimex.com/Products/IoT/ESP32/ESP32-CoreBoard/

I didn't get value from the sensor's analog pins, Is it only works with this sensor arduino or How should I do a pin connection?
I'm waiting for your help

Hardware-wise SHIELD-EKG-EMG should work with ESP32 without much issues. The ESP32 design has ADC pins that work up to 3.3V. SHIELD-EKG-EMG is set by default to 3.3V operation and the analog outputs are also at 3.3V. Some software adjustment would be required, of course. Connection and software suggestions can be seen in this tutorial:
