MetaHealth is the HR and GSR version of the sensor platform and comes with an optical pulse sensor and lead based galvanic skin response sensor. The sensor allows you to measure the heart rate of the user from the skin as well as emotional and sweat based responses (electrical conductance of the skin acts as an indicator of psychological or physiological arousal).

There is an LED and push button switch on the board.

The board is powered by a rechargeable lipo battery.

The board is based on the nRF52 SOC from Nordic built around a ARM® Cortex™ M4F CPU and Bluetooth Low Energy.

The off board memory stores the sensor data on the MetaSensor to be retrieved at any time by your Device (Smartphone, Hub, Tablet or PC).

Sensor data is available:

  • as a CSV file on your Device once the Stream or Download finishes (using the MetaBase App)
  • as a CSV file in the MetaCloud once the data is uploaded (using the MetaBase App or our APIs)
  • as a JSON array in your code (using our Python/C++/C#/Java/Javascript/Swift APIs)
