1-Wire sensor

Information

Using the 1-Wire bus is an easy way to add multiple sensors. This can be temperature or humidity sensors. During the startup of TerrariumPI all the sensors that are connected to the 1-Wire bus will be auto detected.

The 1-Wire bus is enabled by the installer and therefore, it will work out of the box. Use physical pin 7 (GPIO 4) for the data wire.
