[Training Camp_Advanced Class] Internet of Things Smart Socket

I am a novice. I learned a little bit about the 89C51 microcontroller when I was in school. This time I participated in the 2020 EDA Summer Training Camp and received a lot of goods: According to the teacher’s plan, the EMW3080-WIFI module is connected to the Alibaba Cloud IoT platform, and the temperature and relay are reported through the MQTT protocol. For switch information, I used Tmall Genie and mobile app to monitor the temperature and control relay switches; I added a relay action indicator LED5 (convenient for observation) and a DC5V power supply slot (no need to always plug in USB to work), and used EDA to draw circuit diagrams and make pcb.

Jiali creates singles boards and ships them 24 hours a day, which is awesome! BOM It is very convenient to place an order in Lichuang Mall, and the logistics is also very fast! Start welding and debugging your own protective cover

When debugging, I encountered that the USB to serial port could not be connected, and the voltage of the microcontroller was wrong. Then I compared these problems with the EDA teacher's solution and solved them one by one! With the help of teachers and classmates, I optimized the PCB routing, isolated strong electricity and weak points, hollowed out the antenna, etc.!

At present, the PCB has been made to control the relay action with buttons. The intelligent control using Tmall Genie and mobile app is still being debugged and will be updated later! In short, I came to the right place this time and learned a lot. Thank you Lichuang EDA. I hope to hold more learning opportunities like this in the future! The more we do, the better! !

On August 22, the video of the successful debugging of the 220V power strip desk lamp controlled by the app was updated.

The video of successful debugging of Tmall Genie controlled 12V LED light strip will be updated on August 23.

Postscript: The assignment was completed perfectly under the guidance of the teacher and classmates. The 2020 Lichuang EDA [Training Camp_Advanced Class] is coming to an end. For me, this is not the end, but the starting point for me to enter the Internet of Things! Finally, I would like to thank Lichuang EDA again and the students in the training camp for taking me into a new field in these short 20 days and opening a door for me to enter the Internet of Things. I wish the students success in their studies. The future is bright and I wish Lichuang EDA will get better and better! Achieve corner overtaking as soon as possible! !
