## Article

his is what the board looks like. It includes the schematic and Keil 4 source code. The DHT12 is the second generation, with higher precision than the first generation

. Previously, I used an open-source microcontroller networking protocol stack, FuIP, based on the ENC28J60. Recently, I've been using a W5500 network chip and an STM32F103 MCU for control design. Once connected to a router, it can automatically obtain/fix an IP address. Device control is via a mobile app or WeChat, allowing control of the device's built-in relays and viewing temperature and humidity sensor readings.
This terminal's PCB schematic and source code are open-source to facilitate expansion and improvement.
