Hi Ariel, Yes, there would be a tradeoff. I used the term "heatsink" very loosely. I had in mind a small piece of copper tape or foil, attached to one of the leads of the part. This way, you enhance the thermal conductivity from the air directly in to the die of the sensor. I have not done tests here - it could well be that a bare sensor would be faster.
