Algorithm 4 Wireless sensor measuring T, RH, and light intensity
1:	Initialize components
2:	Get batt. level
3:	whileTruedo                          ▹ Main app. loop
4:	Process BLE events
5:	if (1 min. passed) then
6:	if (batt. level and light data from RAM > thresholds) then
7:	Power up sensors
8:	Wake up all components
9:	Measure T and RH, save data to RAM
10:	Get light intensity, save data to RAM
11:	else
12:	Increase postponed measurement counter
13:	end if
14:	Get batt. level, save data to RAM
15:	Power down all sensors
16:	Prepare for low power mode
17:	end if
18:	Update advertising payload with data from RAM
19:	Enter low power mode
20:	end while
