How to control relay through http string

We have learned the communication protocol of the device KC868-H8. And we can control the relays of the device to open and close in LAN mode.   As mentioned earlier, there were some differences in the instruction parameters used in remote control, and today we will plug in the wings of remote control for the device, so…

Anlysis KC868-H8&H32 Communication Protocol

Now, we will start to overall analyze the device communication protocol, and check how it is communicated with the other devices. The KC868-H8 and KC868-H32 are the different models with different quantities relay. The protocol is general used. First, we list all the content of the communication protocol. All of the below, when the device…

Uair development board shell install

 Uair temperature and humidity development board shell install. There are interface of temperature sensor, humidity sensor and PM2.5 sensor on the PCB board (PM2.5 sensor is not standard, pls buy if required). You can install it directly on PCB board, temperature and humidity sensor is recommended to install for extension to ensure numerical accuracy.…
