Versatile Bio Sensor Guide: Temperature
Understanding the temperature sensor on the Versatile Bio
What it measures
The temperature sensor (TEMP) measures temperature changes at the site of the probe as voltage changes.
Research Applications
Physiology, sports, kinesiology, biomechanics, etc.
How to use
The probe should be placed where temperature should be measured. It can be attached to the body with appropriate medical tape or adhesive. After that the connection between the sensor and the amplifier has to be set.
As with any temperature sensor, direct sunlight can alter the recorded temperature drastically.
How to clean
To clean and disinfect the sensor, do the following:
- Disconnect the sensor from the Versatile Bio.
- Use Clinell Universal Wipes.
- Let it dry before using.
- Autoclave is not recommended.
- Do not immerse the device in any liquid.

Visualization filters
A data visualization filter is not necessary for the temperature sensor. For live data viewing, you will have to reduce the data scale for the analog channel until the signal is visible.
Data file
Sensor Range: -50 degrees C to 105 degrees C in air, -55 degrees C to 70 degrees C in fluid
Dissipation Factor (in air): 3 mW / degree C
Thermal time constant (in air): 75 seconds
Data is reported as analog voltage in µV, listed as (analog V) in the formula below. To convert to temperature in C, use the following:
In MS excel, the conversion formula would look like this (analog V values in µV as recorded by the temperature probe in column A, enter formula between [ ] marks into B, C and D):
A1 = Recorded (analog V) value
B1 = [=56000/((3.3/A1)-1)]
C1 = [=1/(0.003354+(LN(B1/10000)/3435))]
D1 = [=C1-273.15]
C1 = Temperature in degrees K
D1 = Temperature in degrees C
