[Tuya Smart] Xiaow-WB3S-Temperature and Humidity Meter

Overview

V1.0 function description (current):

1. 1.3-inch OLED displays time, date, temperature, humidity, power and other data
2. Press the buttons to set related functions.
3. Use DS3231 as a clock IC to provide more accurate time when offline.
4. Use SHT30 as a temperature and humidity sensor, which has better dynamics and higher accuracy.
5. Use VEML6030 to sample the surrounding ambient light to realize automatic adjustment of OLED brightness and turn off the screen at night.
6. Realize APP control and view current environmental data through Tuya Smart’s WB3S wireless module
