battery life

[arden]

I knocked up some door sensors with a nano and a 2300mAh 18650 using the sketch in the demo page

problem is Im only getting about 3 days battery life have verified the capacity of the batteries in my opus and the batteries are good

Ive always used mains power on a usb for my temp sensors this is my first attempt at a battery one

would I be better using a different arduino I was hoping for it to last months not days

any help would be good

thanks

I've ordered some 3.3V version Arduino Pro Minis and will try again

Did you do it all right? Everything works now?

Has your issue been resolved? I'm interested as I'm in a similar situation at the moment.

@HectorAllen - there are many examples on battery operated nodes. I have nodes running for 1.5 years measuring both temp, humidity, open/closed states, pulses and other stuff. To be able to do this you have to modify the nodes - its not possible to run a nano, 5v pro mini or uno out of the box and get a long life.

@sundberg84 Indeed!

it is enough to connect a more capacious battery!
