I have a "Pyroelectric Passive Infrared Sensor" and I want to know how to make a presence detector, simply and with minimal component (and Arduino).
It's look like this sensor RE200B
Do you think that it is possible to directly put the Source (or Drain, I don't know), on an analogic port ? Otherwise, how must I proceed ?
Ps: I'm beginning to really love this forum and this community. It's really pleasant to chat with interested people, to find answer... Receive hello from a young French
