Algorithm 1 Wireless sensor application main activities
1:	Initialize components
2:	Set sensors parameters
3:	whileTruedo                          ▹ Main app. loop
4:	Process BLE events
5:	if (1 min. passed) then
6:	if (batt. level or light data from RAM > thresholds) then  ▹ From prev. active period
7:	Power up sensors
8:	Wake up all components ▹ Can be executed even if device was not in low power mode
9:	Measure T and RH, save data to RAM
10:	Get light intensity, save data to RAM
11:	Perform gas measurement, save data to RAM
12:	Put all components in sleep mode
13:	Power down sensors
14:	end if
15:	Get batt. level, save data to RAM
16:	end if
17:	Update advertising payload with data from RAM
18:	Enter low power mode
19:	end while
