Hi,
If i use a Grove Xbee Carrier ( seeedstudio.com/wiki/Grove_-_Dust_Sensor ) ?
From what i understand, Grove Dust Sensor requires a voltage between 4.75v - 5.25v.
I saw that there are PIR sensors that require 12V.
I guess the general question would be, how can i use Grove XBee Carrier with sensors that require more than 3.7v ?
