Here is the response of a new temperature sensor.  This is the response (in volts) when the sensor starts at 0^oC and is suddenly placed in surroundings at 38^oC.  Answer the questions below for this sensor.

• What is t (the time constant)?
• What is the sensitivity of the sensor (volts^oC)?
• If the sensor is moved suddenly from 0^oC to 25^oC, how long will it take the sensor to get within 1^oC (i.e. to 24^oC)?
