I have a problem with connecting a PIR sensor to the Sodaq One. When I connect a PIR sensor to an Arduino One board all is working well and I could detect a movement. But when I connect the PIR sensor to the Sodaq One it looks if detecting fails and the lines is going high and low.
Has anybody experience with connect an Adafruit PIR sensor the Sodaq One.
Could you provide a link to the specific sensor?
I think the problem is the input voltage of the PIR. Please folllow this link to let work the sensor work on 3.3 v
