The Temperature Sensor has been designed for monitoring very small temperature changes in the peripheral extremities. A stressful event, arousal or in other words, sympathetic nervous system activity, can lead to a vasoconstriction in the peripheral extremities, causing a decrease in temperature. It can be used for several biofeedback applications.
Temperature can be expressed in Celsius or Fahrenheit. The Temperature Sensor can measure changes smaller 1/1000th of a degree.
The Temperature Sensor uses a thermistor, a small point probe which is usually placed on the palmar surface of one of the fingers, often the non-dominant hand. In order to prevent contamination by air flow, the sensor is secured by placing tape over the measuring tip/thermistor. The sensor is usually secured by placing an extra piece of tape in the middle of the finger.
Special tape is included with the Temperature Sensor for NeXus.
Use the Respiration Sensor in combination with the Temperature Sensor in order to monitor both breathing and temperature.
The specifications of the Temperature Sensor are:
|Accuracy||0.0001 degree Celsius/Fahrenheit|
|Range||10 - 40 degrees Celsius (50-104 Fahrenheit)|
