1.10. Analysis of IOT equipment life-cycle#

In this section we will analyse the consequences of the environmental footprint of the lifecycle of typical IOT equipment. We will use the devices listed below, where Power draw is in Watts, Power use is in kWh/year, Use emissions is in kgCO2e/year, Manufacturing emissions is in kgCO2e, and Lifespan is in years.

Power draw Power use Use emissions Manufacturing emissions Lifespan
Name
Sensor 1 1.0 8.76 4.21356 10 10
Sensor 2 0.5 4.38 2.10678 20 10
Disposal 0.0 0.00 0.00000 3 1
Camera 1 10.0 87.60 42.13560 20 4
Camera 2 7.0 61.32 29.49492 30 5

From these devices we will make the following combinations:

Name Old device New device
0 S1 - S2 Sensor 1 Sensor 2
1 S1 - Disposal Sensor 1 Disposal
2 C1 - C2 Camera 1 Camera 2

On these we compute the break-even point in years, and in % of the life-span of the old device:

Old device New device Break-even years Break-even % lifespan
0 Sensor 1 Sensor 2 9.493160 0.949316
1 Sensor 1 Disposal 0.711987 0.071199
2 Camera 1 Camera 2 2.373290 0.593323
