I have a TMP36 that I am using with a Spark Core. I have gotten it working and (what I believe to be) accurate.
I still have so much to learn as far as electronics but I wanted to ask the experts here regarding the particular setup.
The Spark Core has the 3v3’ going to the TMP36 and I have it going to ground. I have the Vout going to A7. I also have a 103 ceramic cap shunting the Vout to GND.
I was looking at this post from Simon Monk where he pulled up the datasheet for the TMP36 and suggested using a 20k or 47k Ohm resistor across Vout to GND. I have a 0.01uF in place of that.
So, my question here is would it be acceptable and equatable to handle that on the software side by doing this:
I have that in place and I am getting extremely steady values but I don’t know if it is the cap or the internal pull-down resistor or a combination of both.
