DOC TO BE COMPLETED!

The documentation is not completed is will be edited in the coming days. Thanks!

Todo:

• Demo firmware for AWS IoT Core
• Demo firmware for Tuya
• Test OTA

Todo next version (v1.3):

• Fix XOR footprint
• Fix reset button
• Fix battery socket pads - invert polarity
• custom version with SIM card for IIOT
• Smart reset IC

Smart Door/Window sensor

The focus of this project is to prove how it is possible to drastically reduce the power consumption(in deep sleep/standby) of battery-powered smart devices by developing a customized power latch. Better design of smart devices would ensure a longer product life cycle.

Power consumption

Measurement range of PPK2

The current was measured with Nordic's power profiler kit , knowing that the current measured is less than the measurement range of this power profiler. I did several tests to verify the accuracy of the data. In any case the accuracy of the data, the consumption would be less than 200nA and this is a very good result considering that a similar device at a power consumption of 6-8uA.

1. Reed switch version

The consumption in deep sleep(POWER LATCH) is the same whether the magnet near the sensor or not.

...in the coming days add more screenshots...

2. MAGNETIC SENSOR IC(S-5701) version

deepsleep: 300nA

...in the coming days add more screenshots...
