KiCad files for an easy circuit to build a motion nightlight yourself
- 1x The PCB in this folder, printed e.g. at PCBWay - 1x 3.2V LiFePO4 battery in AA form factor - 1x AA battery holder for THT mounting - The HC-SR501 PIR sensor. And because this also would act at day time, we also need: - An LDR, a light-dependent resistor, which can be installed into the HC-SR501 to make it only act at night time. See that great video of Clive: https://www.youtube.com/watch?v=2dxhbXHYEG0 - 1x MOSFET. Probably most FETs (ha ha, MOSt FETs... ha ha) are fine, just pay attention that the thermal pad is connected to drain, as the MOSFET bed on the PCB is connected to drain! But…

Motion nightlight: common questions
How big is the Motion nightlight PCB?
The Motion nightlight measures 70.2 × 39.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Motion nightlight?
5 components, from 5 distinct parts. The full bill of materials is listed on this page.
Where can I download the Motion nightlight design files?
From the ezcGman/motion-nightlight repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Motion nightlight design in my own project?
The repository has no license, so all rights stay with ezcGman. Use it as a reference, and ask the author before reusing the design.
