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.

Powered by CR2032 battery.

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.
