So I'm getting into GPIO and the first thing I want to do is connect a sensor and a RF controller. The thing is both 'sensors' require the same GPIO pins, so my question is can I still use both with a breadboard?
The RF sensor requires GPIO pins 1 to 26 and the sensor requires a 3.3v power pin, a ground pin and a GPIO pin so basically all Id need to do is use a different GPIO pin and ground pin for the sensor but what about the 3.3V power pin since its already being used by the RF controller?
The DHT22 doesn't use a specific protocol, so it can be connected to any GPIO pin not used by another sensor. Assuming your second diagram showing the 26-pin header shows the pins used by your RF sensor as those in lighter green with a label, any of the darker green pins without a label should therefore be fine for the DHT22.
As pointed out in a comment, +3.3V, +5V, and GROUND can be shared between as many devices as needed provided there's enough power for them.
