ProtoCentral tinyGSR is a Galvanic Skin Response (GSR) / Electrodermal Activity (EDA) measurement breakout board that allows you to measure and track your physiological responses in real time. GSR measures the changes in electrical conductivity / Electrodermal acivity of the skin, providing valuable insights into a person's emotional state and stress levels. When a person is emotionally aroused or stressed, their sweat gland activity increases, which can be measured as changes in the electrical conductivity of the skin.
tinyGSR contains onboard analog op-amps to measure this change in resistance and helps you to easily interface this with your microcontroller system using just a digital interface. tinyGSR can be a powerful tool for anyone looking to better understand their body and emotions. The tinyGSR has Qwiic compatible connector, in addition to standard breakout headers to just plug it into any compatible board with no soldering required.
