Temperature Sensor

Post by jonatj »

I purchased a temperature sensor for my arduino uno. It came with a 4.7K resistor. Throughout the tutorials and data sheet I don't see this being used with the temperature sensor. Should I be using this resistor as well?

It was entirely my mistake. I thought I had ordered the TMP36 (analog) where I had ordered the digital temp sensor. I apologize for the confusion!!
