It can be powered in two methods one is through external supply through VCC ranges from 3V to 5.5V and other one is through the data line which is also called as parasite mode, in this mode the sensor VCC is connected to GND and the power is taken through the data pin. Thus is it easy to connect it with Arduino and other microcontrollers which takes only 1 GPIO pin as no other components are required except a 4.7k ohm resistor which is connected in series to data pin from 5V supply.
