This project was made during the first part of my semester doing the thematic semester Internet of Things (IoT). I made a simple system for small greenhouse owners.
It consists of 2 part. A software part and a hardware part. The software part is a Nodejs server that interacts with the hardware part and with a website. On the website you can see the current rain forecast in your area. You can also see the temperature inside and outside of your green house. You can also set your desired temperature for your greenhouse. Based on those 3 factors the hardware part will open and close the window of your greenhouse.
The hardware part consists of a Wemos D1 mini, two DHT-11 and a 9g servo. A Wemos D1 Mini is a micro controller. A DHT-11 is a temperature and humidity measuring sensor. A 9g servo is a small motor.
During this project I learned how to write code for a micro controller. Also, I learned the basics about some hardware components. And I also learned how to make A webserver in Nodejs.
