Humidity sensor - without resistor?

Other Hardware General Electronics
1

Hey

I was given 3 parts by my teacher. The arduino, an SD shield and the humidity sensor (AM2302)

Now. Is it possible to connect the sensor to my arduino without a breadboard and resistor?

If so, I have the ,data(yellow) +5 volts (red) and ground (black), right?

Where should what go in the arduino if it's possible.

Thanks in advance :slight_smile:

What arduino do you have and which SD shield? I'd recommend using a resistor (10k ohm should work), I suppose you could solder the resistor to the humidity sensor then connect the other end of the resistor to your arduino so you wouldn't need a breadboard/pcb.

You can plug everything into the arduino using any random digital pins you want to, just make sure the code reflects the pins you're using.
