There is a recommended circuit on page 7 of the data sheet
The transistor isn't critical, any small NPN should work fine.
1000 ohm should be ok for both resistors
NPN is one of the two types of bipolar transistors, consisting of a
layer of P-doped semiconductor (the "base") between two N-doped
layers. A small current entering the base is amplified to produce a
large collector and emitter current. That is, when there is a positive
potential difference measured from the emitter of an NPN transistor to
its base (i.e., when the base is high relative to the emitter) as well
as positive potential difference measured from the base to the
collector, the transistor becomes active. In this "on" state, current
flows between the collector and emitter of the transistor. Most of the
current is carried by electrons moving from emitter to collector as
minority carriers in the P-type base region. To allow for greater
current and faster operation, most bipolar transistors used today are
NPN because electron mobility is higher than hole mobility.
