| - | ===== UniPi temperature sensor ===== | ||
| - | The [[https://www.unipi.technology/1-wire-temperature-sensor-p63?categoryId=3|UniPi 1-Wire temperature sensor]] is equipped with RJ45 connector, so it is easy to connect to [[en:hw:02-neuron|UniPi Neuron]] controllers and [[en:hw:06-1-wire-hub|UniPi 1-Wire hub]]. In order to connect the sensor to UniPi Axon, you have to cut off the connector, put on the ferrules (see [[en:hw:05-guidelines:01-wiring-guidelines|wiring guidelines]]) and screw it to the Axon's 1-Wire connector according to [[en:automation:02-glossary:04-1wire#wire_on_unipi_axon|this pinout]] | ||

| - | The sensor introduces a 4 wire connection for better reliability of larger network, which can be converted to 3 wire version for simplification. | ||
