What is a 1-Wire sensor?

A 1-Wire sensor is a sensor using the 1-Wire device communications bus. This provides a low-speed data signal and power using a single conductor. 1-Wire is typically used to communicate with small devices like digital thermometers and measurement devices. When a 1-Wire sensor is connected to an environment monitor, the system can be termed a ‘MicroLAN’. The term ‘1-Wire UNI’ is used to refer to sensors other than for temperature or humidity.
