==Connecting Multiple 1-Wire Sensors with TRB141==
The configuration for connecting multiple 1-wire sensors is the same as above.
There’s no restriction or limit on the number of sensors that can be connected to TRB141. However, there’s a limit on how many sensors can be read every second which is up to 75 sensors only.
===DS18B20 connection===
The wiring image is a similar scheme that we used as our guide for connecting multiple 1-Wire sensors on the TRB141.

==Output==
Enable the 'ioman.gpio.onewire' service. You can configure this by following the instructions above regarding [[TRB141_1-Wire_Setup/Configuration#1-Wire_activation_commands|1-Wire activation commands]].
We should be able to see all the 1-wire sensor directories and read their values accordingly.
