Temperature and humidity collection terminal based on Tuya Smart

Overview

Using STM32F411CEU6 (48PIN) as MCU + Tuya Smart's WB3S networking module, the collected temperature, humidity, and light intensity are uploaded to the Tuya IoT platform. It is also equipped with a 1.8-inch LCD screen of ST7735 to display the collected data in real time. Various data, in addition to facilitate later SDK development, led to the redundant pins of WB3s, and connected RGB lights to three of the pins. Comes with USB to serial port for easy debugging, download method is SWD

Equipped with two servo ports, powered by TYPEC.

There is also EEPROM memory 24C08 that stores data such as temperature, humidity, and light intensity.

The cost of the complete set is less than 50 yuan, and most of the consumables are provided by yourself. ~~~~
