For decades, people have searched for ways to store ambient energy, and in the age of Internet of Things devices, this is combined with the desire to power sensors and mobile devices. This project demonstrates a basic eco-friendly implementation of a solar powered IoT sensor.
The IoT Solar Harvester transmits sensor data using a WiFi connection. It is powered by solar energy, which is gathered and managed by an energy harvester (LTC3106) that powers the IoT sensor and stores excess energy into a rechargeable battery, to be used when the solar panel doesn’t provide enough power.
