What is the electricity consumption of a sensor?

The fine dust sensor as a unit needs approx. 1 Watt, if it would run through the whole year, that would be (1W x 24h x 365 days)/ 1000 = 8,76 kWh, so approx. 2,50€/ year.

Dump the usb to serial chip, LDO regulator (use a switching regulator) and the leds and I have it down to 0.5W…
