Hey guys I'm new to the Pi and wanting to make a project for my house to monitor 3 zones with temp and humidity.
Looking around i found the DS18B20 that i can run all on 1 pin from the gpio for the data line. (Dallas 1 wire connection)
However that only does temp, and i need humidity as well. So the DHT22 (or the AM2302 as I will order it) looks like the way to go.
But that does not support the Dallas 1 wire on the i2c and I have not seen anyone out there running more than 1 (been looking for a few hours now)
I will not be using a breadboard, they will go directly to the gpio pins, and will be about 3 meters long (do I need to use another pull up resistor? According to adafruit, there is a 5.1k resistor in the AM2302 already) and from the research I have done, I would have to use the 5V not the 3.3V correct?
And the last is, what software will get this to work with all 3 (I'm assuming some type of python library?) I see adafruit says they have this for Arduino but not for Raspberry Pi...
Thank you in advance
