My plan is a TTN Node, or even a MySensors weather station, or other Arduino based projects to operate completely autonomously as a self-sufficient. This is probably the most simple and cheapest a solar cell and a LiPo as a battery for dark times.
In this post I try to make my Arduino based TTN Nodes more power efficient.
I recently designed a PCB (my first one) that has the components that are important to me.
The idea: anyone can buy / build their own IoT devices and use the existing community network. If there is no gateway (reception and transmitting station), you build one yourself and your environment can use it as well. The ranges are about 5km. Absolutely free!
On this page I introduce you to all my projects. I hope you enjoy reading, commenting and getting new ideas! Have a nice day 🙂
