[Tuya Smart] Cloud Temperature Monitor

A temperature and humidity sensor based on Tuya IOT platform

This project is developed using Tuya SDK, which enables you to quickly develop branded apps connecting and controlling smart scenarios of many devices. For more information, please check Tuya Developer Website.

feature design

• [x] OLED display
• [x]  Temperature and humidity monitoring
• [x] Temperature and humidity information upload
• [ ] Get local weather
• [ ]  Change the display status of the REB light according to the weather
• [ ]  Utilize Vuforia engine to implement AR interaction with sensors

##hardware design

STC8A8K64S4A12 is used as the MCU master control. The temperature and humidity sensor SHT30 and the display OLED communicate with the MCU through IIC. The Tuya module WBR3 interacts with the MCU through the serial port.

The problem found so far is that the MCU and Tuya module cannot communicate through hardware serial port 4. It is guessed that there is no external pull-up resistor, so communication can only be done through external serial port 1 via a jumper.

software design

The Vuforia engine is used for object recognition in Unity, and the temperature and humidity information is displayed in the form of AR. (But it's not finished yet)

The current implementation effect (only using Vuforia to identify and display an object, and the Tuya SDK has not yet been transplanted)

The following is a basic function test diagram, that is, after the module is connected to the Internet, the status value is checked through the mobile phone (I use Tuya’s public board, and the app I implemented has not been transplanted and tested yet)
