[Tuya Smart] IoT temperature and humidity sensor +541726A

Based on Tuya smart IoT module and STM32F103C8T6 (if the chip material is too expensive, it can be appropriately replaced with a domestic chip of the same type), SHT30 IoT temperature and humidity detection module

The sensor is powered by a Type C power bank. The reason for not using batteries for long-term power supply is (I will not calculate the power consumption). It is better to directly power the power bank or use a low-power charging head for long-term power supply.

Use an AMS1117 to convert 5V to 3.3V to power all component modules.

At the same time, SHT30 was used for temperature and humidity detection. I had used DHT11 for temperature and humidity detection before, but the accuracy of DHT11 was too low, so this time I replaced it with the recommended SHT30.

At the same time, an SPI seven-pin OLED screen is also used for real-time display. Anyway, if you put this little thing on the edge of the table, you can also see the real-time temperature and humidity in the blink of an eye.
