[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.
