A No‑Compromise Solar Power LiFePO4 Solution for Arduino Projects
•
I have been designing and building a weather station to put in my garden at home. It will be a one-off project so I don’t need to compromise on cost – instead, I want something that will be reliable and, if anything, slightly over-engineered. This particularly applies to the power source – it has to be exclusively solar powered and there must be minimal risk of battery fire as it will be located close to a…

Nano 33 IoT: Testing with solar power and BQ25185
•
My objective was to build a battery powered environment monitoring station using an Arduino. It might be an outdoor weather station tracking temperature, pressure and humidity or something to track indoor temperatures. Long battery life was a primary concern. In a previous article, I investigated how to minimise power demand and select the best combination of batteries (see my earlier article Nano 33 IoT Testing Battery Options and Low Power Mode). The final step, described here,…
