I'm Using an Electron to track the temperature inside a truck box. I could not connect to AC because it's a refrigerated box and I could not modify any part of the box.
I use 2 dallas sensors to read the temperature every 15 minutes, after I create a Json that has been sent to particle with all the info. After this, I deepsleep the machine.
The problem is the battery life, I'm using a 3,7v 6000mAh and the duration was only a week.
Is it possible to save energy, or increase the battery power, or increase the performance?
