i have a raspberry pi connected with two ds18b20 temperature sensor. -sensor1 is fixed on the outside of my garage (distance 20m from raspberry pi) -sensor2 is just connected in a breadboard near the raspberry pi. Everything is working well.
I decided to add sensor3 located outside and from 20m from the raspberry pi.
Now when i type : cd /sys/bus/w1/devices
if find this: c0-40a000061005 c2-246056869800 c2-247056869000 d0-008000001000 w1_bus_master1
instead of : 28-..... 28-..... 28-.....
each sensor ref should be start with 28-.....
what is happening with my sensors? If unplugged the sensor1, then everything is well
if i unplug the sensor3 and let only sensor1 and sensor2 everything is well.
Which modification do we have to do when sensor are located far from the raspberry pi?
I have one of these stoopid simple devices...and it works!
My Pi is just a Time waster.. I've finally realised
You might want to try a Raspberry Pi DIY website and not an audio forum. Just a thought.
at least it's not a post about MQA. :-)
