Power consumption


Tilman

Question

Hi,

I am using a brand new device with a mechanical contact switch attached (used as a door sensor).

I was wondering that the battery was empty after a few days.

I did some further investigation on this issue and measured approx. 20mA powered at 9V DC and approx. 12 mA, if powered at 18V DC.

This is a totally unexpected behavior and makes it very hard to use while battery powered.

Is there any way to lower the power consumption (e.g. sleep mode, ...)?

 

I didn´t find any command related to this issue in the spec.

 

Any help appreciated.

 

Thanks in advance for all your time.

 

BR

    @Tilman That doesn't work, you need a powersupply.

    implant and ubs will drain the battery in no time.

  • Hmm. Thks. for the answer.

    Very small device, very high power consumption.

    Might be, adding a sleep mode with external or timed wakeup could do the trick.

    @Tilman It's working as a repeater so it is Always listening.

    A battery powerd device goes to sleep mode and only wakes up to report something,

     

    use a powersupply or a car battery :)
