Optimize the power

Meenakshi · ‎2024-09-25

I'm using STM32F423ZHT6 MCU board for Smart Lock operation. Here, I'm using 2 limit switches.

Based on the Limit switches door is lock and unlock. But, the motor is always on state so it consume more power. How to reduce my power consumption.

Please anyone help me.

So don't do that, then!

Turn the motor off when it's not needed.

A complex system designed from scratch never works and cannot be patched up to make it work.

Hi @Andrew Neil,

It is a smart lock project. So, if I turn off the motor, how do I open the door? I need any guide to reduce the power consumption.

Surely, the motor only needs to be powered during the actual locking and unlocking process?

While the lock is in the steady 'locked' or 'unlocked' state, it shouldn't require any power at all?

If that's not the case, then it's a fundamental flaw in the lock's hardware design - you can't fix that in software!
