From seeedstudio.com/wiki/index.p … ion_Sensor:
Specification
Operating Voltage: 5V
Operating Current(VCC = 3V): 100uA
Operating Current(VCC = 5V): 150uA
I don’t get it… can it operate on 3V or not?
I use the 3.3V Arduino Pro Mini…
thanks
The Operating Voltage is from 3v to 5v, so Arduino Pro Mini is ok.
