I want to monitor temperature and humidity on the rooms of my house.
I’ve Cat.6 cables that can be used to connect sensors.
I want to monitor all centrally, using Raspberry.
The maximum cable length is around 10 meters.
I’ve tried with DHT22, but I’ve some instabilities (perhaps they are not connected properly).
Do you suggest something?
Thanks for answering.
I have connected to 5V power of Raspberry, with a pull-up to 3V at sensor side, made with a divider from the 5V.
How you connected it?
The SHT31 is over I2C, so I assume it does not cover 10 meters of cable length.
