Thermal mass and the TI HDC1000EVM

Thermal mass:

The thermal mass of the TI HDC1000EVM is very low which is excellent for instantaneous temperature or fine resolution

temperature sensing.  However you may want a more moderated response.  In graphing my sensors over time the TI HDC1000EVM

was wildly erratic but it is mounted outside and the low thermal mass means the sensor reacts to the momentary temperature.  If a

breeze blows it will change the temperature to reflect the instantaneous temperature and not the average temperature.

Since I wanted a nice smoothed graph of outside temperature I added thermal mass by putting some modeling clay around the sensor.

What ever you use it has to be non-conductive of course.  Now I get a nice smooth graph of outside temperatures.
