[1] The thermal time constant is the time taken for the sensor to reach 63.2 % of the total temperature difference. For example, if a sensor
with a temperature of 25 °C is moved to an environment with an ambient temperature of 100 °C, the time for the sensor to reach a
temperature of 72.4 °C is the thermal time constant.
