I want to connect both a fan, set in slow cooling mode, and a DHT22 sensor to my RPi.
fan in cooling mode:
- power wire: connected to pin 17
- ground wire: connected to pin 20
and it works fine.
Now I want to add a DHT22 sensor, whose vendor sent me the connection schema, that is the following:
- red wire = power, connected to pin 1
- blue wire = data/GPIO, connected to pin 3
- black wire = ground, connected to pin 6
Now, how can I get data from my DHT22 sensor?
Is it possible to do it without using a board?
