SparkFun Arduino IoT Weather Station Category_Mechanics and Materials/Construction Materials if it is connected to

if it is connected to a microcontroller

and (3) a 3-pin 0

Since the current in parallel mode is split between two paths

Use only one microcontroller pin to control as many as you can chain together

that is ok too
