The idea is to use Wio link to implement an indoor weather station. The difference here is that the weather station will be attached (or glued) to the inside of a glass window in your home. Wio link will be powered by a li-po battery, which will be charged by a set of solar panels also glued to the windows (facing the outside, of course).
Wio link will read one analog temperature sensor (LM35 for example) and one humidity sensor (Si7021 or DHT11) and periodically send data to an online storage/log iot service (such as Adafruit.io, Sparkfun, ThingSpeak, etc).
