I am attempting to get an ESP8266 to read temp from an analog temp sensor (TMP36). The ESP is on the Adafruit HUZZAH ESP8266 breakout. The board has a single analog pin that I believe will allow me to do this. The description of the board says the analog input has a 1.8v max voltage. I will be supplying the TMP36 with 3.3v.
Do I need to divide the output of the TMP36 to get a proper reading? How should this division be done? Once it is done, do I also then multiply the reading from the TMP36 by they same amount it was divided?
