[Tuya Smart] Temperature and humidity sensor (MCU) based on Tuya Smart

Overview

Function description:
1. You can check the indoor temperature and humidity status through your mobile phone, allowing you to better understand your living environment.
2. Real-time display of temperature and humidity through OLED
3. When the temperature and humidity are too high, the buzzer will alarm
4. Display temperature, humidity and weather through dot matrix
Hardware Configuration:
MCU: STC8A8K64S4A12 chip
USB to TTL downloader
With 0.96 OLED display
With 8×16 dot matrix display
The sensor uses SHT30 temperature and humidity sensor
An external 2K PROM memory model AT24C02
Buzzer is used to remind high or low temperatures
LED lights for status display
Press button to debug
The WiFi module uses Tuya Smart's WBR3 and can be connected to Tuya Smart APP for easier viewing.
