Dallas 1-wire temperature sensors can be connected in either powered mode using the GND, 3.3v and 1-wire data pins, or in parasitic power mode using only 2 wires of 1-wire data and GND. All sensors connected must be either powered or in parasitic mode, the 2 cannot be mixed together. | Dallas 1-wire temperature sensors can be connected in either powered mode using the GND, 3.3v and 1-wire data pins, or in parasitic power mode using only 2 wires of 1-wire data and GND.
