ADS1299 ESP32 or TGAM ESP32?

Last Updated on January 11, 2023 by pg@petergamma.org

• This project uses an ADS1299 with ESP32:

• Here, we can find the Facebook instruction:

• is uses only one channel

• Why then is a ADS1299 with 8 channels used?

• This project uses OpenBCI with MQTT:

Paper of pioneers of OpenBCI with Home Assistant who connected an EEG headband to an OpenBCI Cyton board which is connected over the OpenBCI Bluetooth dongle to an Odroid XU4 to an MQTT cloud and contolled a light bulb over ESP32 and a TV over a Raspberry Pi 3B+ which controls a TV over a DIY IR remote control

• For us, it appears to be a complicated path over MQTT, for instance if we want to connect OpenBCI over MQTT to Home Assistant

• To connect individual EEG modules with a 16 bit A/D converter and an ESP32 module seems to be a quiet easy path to connect it to Home Assistant, as described previously in this journal

• The instruction shows an ADS1299 with an ESP32, but uses only one channel

• Why do choose a ADS1299 chip then?

• We do not know of an instruction with an ADS1299 which connects 8 channels to Home Assistant, and we do not know of a paper which studies this either

• We do not know of a project, which connect an 8 channel OpenBCI Cython module to Home Assistant

• Why to choose then a ADS1299 chip? Are there any advantages?

• We can also use single EEG modules and connect it to ESP32 and to Home Assistant.

• Many Home Assistant sensors where connected in this way

• We can study these instructions and modify themselves

• We previously made bad experiences with Texas Instruments products as for instance the Texas Instruments ADS1299 demo boards

• posters in the EEVBLOG advised us how to make it save to human, but we found better products

• the result was, that we left the EEVBLOG, and did not find a satisfying solution with the ADS1299.

• was this chip not designed to lower the costs of EEG devices?

• Texas Instruments has nothing to offer how to connect the ADS1299 in an easy way to Home Assistant.

• To use individual TGAM modules seems to us easier and connect them over ESP32 to Home Assistant, than to use a ADS1299 with OpenBCI over complicated chains with MQTT, or with ADS1299 demo boards, which are not save to humans, and we do not know of anybody who uses this boards on a regular basis.

• Texas Instruments seem to have nothing to offer to solve our problem in an easy way, to connect physiological sensor data for instance of the ADS1299 to Home Assistant.
• One advantage of OpenBCI is the GUI. But it would be highly desirable, that a tested and working device is available somewhere, and that it is connected to Home Assistant.
