I’m a software guy, but dabbling in the electronics aspect using the Arduino and love it…
I’ve got multiple TMP36 sensors hooked up via Category 5e cable (less than 1 foot) and have that hooked up to the 5V, Ground and Analog Sensor ports on the arduino. I’m getting voltages from the sensors back at 0.98v, etc - which seems wrong to me.
What I eventually want to do is have 1 Arduino and Cat 5 cable running to each of the sensors (100’ maximum for each sensor).
Does this sound crazy - do I need an Analog to Digital Encoder to get reliable signals back to the Arduino?
