Galvanic Skin Response Sensor (GSR - Sweating)
Description: This sensor measures the electrical conductance of the skin, which varies with its moisture level. This is of interest
because the sweat glands are controlled by the sympathetic nervous system, so moments of strong emotion, change the
electrical resistance of the skin.
Measurement:
Parameter Unit Range
Conductance Siemens 0-20Siemens
Resistance Ohms 10K-100KOhms
Voltage Volts 0-5V
Blood Pressure Sensor (Sphygmomanometer)
Description: Blood pressure is the pressure of the blood in the arteries as it is pumped around the body by the heart. When
your heart beats, it contracts and pushes blood through the arteries to the rest of your body. This force creates pressure on the
arteries. Blood pressure is recorded as two numbers—the systolic pressure (as the heart beats) over the diastolic pressure (as
the heart relaxes between beats).
Measurement:
Parameter Unit Range
Systolic pressure mm Hg 0-300 mmHg
Diastolic pressure mm Hg 0-300 mmHg
Pulse ppm 30~200 ppm
Auxiliar input 1
Description: This are generic inputs for possible a UART interface sensors
Auxiliar input 2
Description: This are generic inputs for possible a UART interface sensors
Pulse and Oxygen in Blood Sensor (SPO2)
Description: Pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin. Oxygen
saturation is dened as the measurement of the amount of oxygen dissolved in blood, based on the detection of Hemoglobin
and Deoxyhemoglobin. Two dierent light wavelengths are used to measure the actual dierence in the absorption spectra of
HbO2 and Hb.
Measurement:
Parameter Unit Range
Pulse ppm 25~250 ppm
SPO2 % 35-100%
