【Training Camp】Smart power strip

1. When the project was first carried out, it was relatively smooth. When it came to 220v voltage monitoring, there was a little difficulty. The bl0937 chip needed to connect the gnd and the neutral line together. Because I had never been exposed to high voltage before, I didn’t dare to do it. Together, after the 220V-5V module arrived, I shorted it with a wire, plugged it in with great expectations, and found that there was no problem. I tested it with a voltmeter and it was perfect, so I continued to draw the schematic diagram, PCB, configure the cloud, and modify the firmware. ,Everything is going smooth! ! 2. Because the school is quite busy and I don’t have enough time, I don’t have 3D printing for a socket shell. I simply connected it to the power and tried it. I feel that the effect is pretty good and the response is relatively fast. Because the Xiaoai speaker is not around, there is nothing I can do. Experiment with the functions of smart home interconnection and try it again when you get home!
