My purpose is to make a tobacco fermentation tank that uses the sun for heating during the day and controls the humidifier through a humidity sensor. The main body of the box is a foam box. I put a tin foil (which can also be aluminum foil) inside, and the opening of the box is sealed with a plastic wrap. This can absorb more of the sun's heat without losing too much heat. At the same time I use the 8266 module and I can monitor data (io.adafruit) in the office. At present my equipment has already started running. However, the humidity curve is not ideal. I will adjust my code to make the humidity curve smoother. At the same time, the current maximum temperature record is 44 degrees Celsius, and it has not reached the target of 50 degrees. English is not my mother tongue, and I don't want to write this in English. It's too hard for me. So the English version of GOOGLE Translator is provided.
