- Power consumption will vary depending on the version of arduino, as well as who makes it.
- The long chip on the bottom(expand on this later) often dictates the power consumption between the same model.
- As the goal is to acheive the lowest possible power consumption, an official version is suggested.
- I have a few different chinese clones, and used the most efficient one.
- Idling at 0.009a with nothing plugged in and low power mode code enabled.
- Mechanical
- 0.009a @ 12.13V
- Sold-state
- 0.000a @ 12.14V
- Mosfet
- 0.000a @ 12.16V
This shows that a mechanical will waste power while the system is idling while Solid-state and Mosfet consume practically nothing.
- Mechanical
- 0.185a @ 11.95V - Would not trigger when powered with 5V
- Sold-state
- 0.028a @ 12.11V - 0.009 @ 5.1V
- Mosfet
- 0.004a @ 12.14V - 0.008 @ 5.1V
This shows that the mechanical consumes more than solid-state and mosfet while triggered and does not trigger with a 5V power source.
- Solid-state
- 1095 Ohm /w 5V power and 5V trigger
- Mosfet
- 5.5 Ohm /w 5V power and 5V trigger
This shows very low resistance with the mosfet while no load is applied.
Mosfet should be the ideal candidate.
- FC-28
- 0.004a @ 5.1V no trigger
- 0.008a @ 5.1V digital trigger
- Need to verify analog trigger consumption
