Use GD32 microcontroller + Tuya module to collect and view temperature and humidity

Introduction: This project uses GD32 microcontroller and tuya's wifi module to collect temperature and humidity. The temperature and humidity module uses SHT30 or DS18B20. By using tuya module to link to Tuya Cloud, the mobile APP displays in real time. When the temperature is lower or higher than the set temperature, Alarm records can be stored in flash. Lead out the remaining IO port of the microcontroller, and you can connect an external relay to control the heater heating or humidifier, or you can connect an external OLED display or digital tube to display the value.

Features

Button function: Click the wifi reset button to enter smartconfig mode for wifi network configuration. Temperature and humidity: Use SHT30 temperature and humidity module or DS18B20 to collect temperature USB interface: It can provide power supply and communication. It uses CH340E chip, which can print system information and facilitate debugging. Microcontroller: Use GD32F103RBT6 MCU. WIFI module: Tuya’s WBR3 module. IO port: Lead out the remaining IO ports of GD32F103RBT6, and can be connected to an external display screen or LED digital tube to display values.

Completion

Schematic and PCB design are complete. Before PCB board is soldered

Demo test of the finished product after PCB welding is completed , and the effect of the lighting program
