Dallas Temperature Component
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
The ``dallas`` component allows you to use your
|
|
|
|
|
`DS18b20 <https://www.adafruit.com/product/374>`__
|
|
|
|
|
(`datasheet <https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf>`__)
|
2018-06-01 18:10:00 +02:00
|
|
|
and similar One-Wire temperature sensors.

|
|
|
|
|
|
|
|
To use your dallas sensor, first define a dallas “hub” with a pin and
|
|
|
|
|
id, which you will later use to create the sensors. The 1-Wire bus the
|
|
|
|
|
sensors are connected to should have an external pullup resistor of
|
|
|
|
|
about 4.7KΩ.
