Grove Mini PIR motion sensor supply voltage

Post by christopher.olofssson » Fri Aug 10, 2018 7:04 pm

Why is the supply voltage rated 2.7-3.3V when there is a voltage regulator with maximum voltage 6.0V and dropout 0.25V? I think the correct supply voltage should be +3.25 to +6.00 Volt? Or have I missed something?

Hi there,

Thanks for point out the issue. We looked at the schematic. The correct working voltage is 3.3~6V. For grove interface, it supports 3.3v and 5V. We will update the info. thanks.
