(Translation: what's the purpose of J1 on the PIR sensor room board?)
This was added to see if power consumption could be dropped further by using a high pull-up instead of the one built into the ATmega. I haven't done any tests in that direction yet.
OK, where to find the documentation of this sensor on the net?Posted 2011-02-15 ago #
There is none :( - did find out that turning the trimpot to left gives best results.Posted 2011-02-15 ago #
