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.
Takeaways: This 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 Skills: To 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.
