Building a device that can run for years on small batteries



With low-energy networks at disposal, to utilize new possibilities the challenge is to build devices that can run for as long as possible without changing energy source. 

TakeawaysThis session is a walkthrough of a mail box sensor that has lasted for over 2 years. It will cover the basic premises of power efficient microcontrollers and sensors. It will also offer practical guides on measuring current consumption and lessons learned.

Required SkillsTo follow along you should have basic experience with the Arduino environment, access to a The Things Network LoRaWAN and knowledge of how to register devices with TTN.

Become a partner.

Become part of The Things Conference and get in touch with tens of thousands of LoRaWAN professionals.
