Translations:1-Wire/12/en

In some cases, the sensor can be connected with only two wires. To do this, connect the power and ground contacts of the sensor, and connect them to the ground of the controller. With this connection, the sensor will take power from the data channel. This method is not recommended because it slows down the polling of sensors, especially if there are several sensors on the same port of the controller: the time is spent on charging the internal capacitances of the sensors with voltage from the data line. This method is not recommended if several sensors are connected at the same time, as the current from the data line may not be enough to charge several sensors
