I already have a simple termometer using an arduino pro mini, an oled display and a dht22. Now I would like to use the same data from the same dht22 on a raspberry pi as well.
My doubt is: can I connect the DHT22 to the arduino and the pi at the same time and read its data on both devices? I only want this because in my situation is not practical to use a new DHT22 for the pi.
Try it!
The thermometer is built inside a wall socket, and the pi is a smart mirror, and I will have to pass wires through the electrical tubes do connect the DHT22 to the pi. That why I ask first, because it will bring me some work just to try it. Everything is soldered to the arduino, so try stuff is more complicated.
I attached my setup (yes. It is 35º celsius in Rio right now, inside the house)
Just connect the Arduino to the Pi, and have the Arduino tell the Pi what it read from the DHT22.
