Version 5 of the Window/Door sensor project this time with ultra low current consumption

*** "Window sensor V5.zip" file added with all the files required for PCBA at JLCPCB.com previous files removed.

Version 5 of the Window/Door sensor project this time with ultra low current consumption and a button input. I have continued to develop the original window/Door sensor from the Youtube video of Makermeik (https://github.com/MakerMeik) and this is the latest version (version 5) At each revision I've tried to reduce the power consumption more and more and with this version the Quiescent current with the Door/Window shut is a around 5.4uA and with the door open or using as a WiFi…

Window-Door sensor-Version-5: common questions

What microcontroller does the Window-Door sensor-Version-5 use?

The Window-Door sensor-Version-5 is built around the ESP-12F, from the ESP8266 family.

How big is the Window-Door sensor-Version-5 PCB?

The Window-Door sensor-Version-5 measures 31.5 × 20.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Window-Door sensor-Version-5?

30 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Window-Door sensor-Version-5 design files?

From the gadjet/Window-Door-sensor-Version-5 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Window-Door sensor-Version-5 design in my own project?

Yes, under the terms of its GPL-2.0 license, which gadjet chose for the repository.

Can I test firmware for the Window-Door sensor-Version-5 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
