Ok, this has been asked twice in the comments, but I can’t find the answer. Does it need the 4.7k pull-up resistor?
Opps just learned that this is a digital sensor. Lets drop it on a free digital pin and see what happens.
I can’t make this work with my Arduino. I have the red wire on 3v, the black on Gnd, and the white on A1. I have also have a TMP36 on A0 wired the same. With my meter, I am getting 3.3v at the solder point but nothing on the white wire. The TMP36 gives me about 0.7v. Did I do something wrong? Do I have a bad sensor?
No public wish lists :(
