Light and shock sensor | nRF52840 | MySensors | OpenHardware.io

Scheme, Gerber file, case models, software are available on github - https://github.com/smartboxchannel/EFEKTA-LIS2DW12-MAX44009-E73C

Two sensors are used, max44009 light sensor (1 ua) and lis2dw accelerometer (1 ua).

Depending on which sensors are installed on the PCB, it can be used only as a light sensor, only as a shock sensor or both.

In the test sketch implemented:

The light sensor measures in Lux.
The shock sensor has five levels of sensitivity.
Two modes of operation: main (working) mode and command reception mode.
The sensor accepts settings: the interval of sending data from the light sensor (in minutes), sending recalculated light data from Lux to watts per meter squared(on/off), the sensitivity level of the shock sensor(5 levels, 1 to 5)
Depending on which sensors are installed on the PCB, it can be used only as a light sensor, only as a shock sensor or both.
