Query: ironbci. Open source. Brain-computer interface with the embedded board
  to monitor the physiological subject's condition and environmental parameters   This manuscript presented brain-computer interface (STM32 and ADS1299) with
the embedded board with sensors to monitor the subject's state and environment.
To reduce power consumption and device size, we used sensors made in
Micro-Electro-Mechanical Systems technology (MEMS) - a gyroscope,
accelerometer, and environmental monitoring sensors: CO2, temperature,
humidity, ambient sound, and pulse and blood oxygen saturation. Data from the
device is transmitted using TCP-PI (UART by Bluetooth) protocol to a computer
or mobile device. Open-source https://github.com/Ildaron/ironbci
