099k. Summary about low-cost high-quality physiological sensor devices which are available in 2024

Why does Peter Gamma from www.petergamma.org not find low-cost high-quality physiological sensor device, altough he is looking for it since years & years & years?

Peter Gamma from www.petergamma.org has studied these devices intensively.

There are instructions available from Adafruit for open source consumer grade bike computer and step counters:

200. BLE Sensors

But consumer grade heart rate monitors are only of very limited use for scientific studies, as you can see in this review:

090. Review of Accuracy Studies of Consumer Grade Heart Rate Monitors: Methods, Testing Protocols, Reference Devices

There are other devices from PLUXBIOSIGNALS:

https://www.pluxbiosignals.com/

• But Peter Gamma from www.petergamma.org does not know of a community of users who uses those.

There is a community of users at www.openbci.com with a support forum

• But users regularly complain that the costs for those are high and they are hardly developed further.

There are OpenBCI made in China alternatives:

099d. OpenBCI made in China – what do we know about it?

• But www.petergamma.org does not know of a community of user who uses those.

HackEEG and PiEEG

• products come and go and seem to be strongly controlled so that they do not find a community either.

Then we have devices which are based on

InfluxDB, A/D converters and InfluxDB:

Why does Peter Gamma from www.petergamma.org not find an affordable EEG device which is based on the ADS1299 altough he is looking for it since years & years & years?

• Especially the example with the Apple watch and Home Assitant shows how superior multi-sensor devices are based on InfluxDB.

And the example of Home Assistant has shown how easy it is to build an open source multi-sensor device.

• Why are there no devices for physiological sensor devices available for physiolgical sensor devices, similar to Home Assistant?

• Because the community for those is too small.And Adafruit will most probably not offer such instructions for the same reason.

So finally these instructions are new and interesting for Peter Gamma from www.petergamma.org

Why does Peter Gamma from www.petergamma.org not find an affordable EEG device which is based on the ADS1299 altough he is looking for it since years & years & years?

• But instructions on YouTube and at other places in the web are often instructions which have been given up by developers and are sold there by demo makers.

So the best solution for Peter Gamma from www.petergamma.org is on the long-term to build up a simple and new device with simple components, and not to look for instructions on YouTube and in the web, but in the scientific literature. And to choose only journals which do not have a conflict of interest, such as the The Journal of Meditation Research (JMR):
