PIR sensor use case

Recently developed my own shelf light for Kitchen. Version 1.

Works perfect.. installated on 15 Mar 2016.

Demo video

Version 2.
An improvement over previous version, replaced the ics with smd versions, 78L05 and 2n2222.

Soldering three 2n2222 on top of each other.

Working as expected.

Size reduced to 4th of previous circuit.
