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.
DS18B20
An easy to use temperature sensor is the DS18B20 sensor Make sure you use a 4.7K resistor when connecting 1 or more DS18B20 sensors.
Setup
Auto detect
This sensor will be auto detected during startup or added by ‘Scan sensors’ in the menu.
In order to use the 1-Wire sensor use the following settings:
Mandatory
- Hardware
- 1-Wire sensor
Types : humidity, temperature
- Address
- Enter the symlink folder name that are available at
/sys/bus/w1/devices/
Ex:28-0115b231f3ff
Other settings can be found at the sensor setup information
