To build our own 3 Channel Gold Standard ECG Device with a Spirometer from AD8232, ADS1115 & Arduino
- AD8232, ADS1115 & Arduino is less than 50 USD
- Four channels 16 bit A/D
- It requires advance soft- and hardware skills
- The instruction presented here is only an AI Overview up to the present day:
- The community which builds such devices is only small
- This setup is future proof. It is cheap, and it only lacks a community which uses it and writes papers about it
This last setup is my preferred choice but needs to be digested. It has 16 bit A/D which makes it suitable for medical and research grade applications. It is the setup for people who are on a budget. It lacks the issues the issues the iWorx TA-220 has and the OpenBCI Ganglion, and that is that these devices are expensive, need to be imported from the United States with high shipping costs and import taxes. For building your own device the last setup is the setup of our choice.
