[Tuya Smart] SoC solution temperature and humidity meter +510162A

Based on Tuya Smart Platform’s SoC solution for temperature and humidity sensor, this time I plan to try both the code-free and MCU solutions. Due to work reasons, I haven’t had time, so I will try the code-free SoC solution first.

Already implemented functions:

1. Monitor temperature and humidity changes throughout the day. If the value exceeds the custom setting, the air conditioner can be turned on (the designed mode and temperature are expected), the humidifier can be turned on, the air conditioner and humidifier can be turned off, etc.;

2. You can also subscribe to phone and text message notification services when temperature and humidity change abnormally;

3. The Tuya app can also control Tuya’s other smart appliances through linkage with weather, PM2.5, air quality, wind speed and other weather changes.

4. You can time, delay, execute and start automation equipment with one click.

5. Can charge a single cell 18650 and use it as a charger;

Tuya Platform: Tuya Smart is a magical platform that allows novices to quickly create high-end works!

Circuit design: Lichuang EDA is a leading domestic EDA company. The open source platform is cool!

PCB production: Jialichuang is a conscientious enterprise, excellent quality and perfect price coexist!

Design:

1.SHT30 temperature and humidity collection;

2. Tuya XR3 WIFI module uploads to Tuya Cloud;

3. Use TPS63001 (1.8~5.5V) to step up and down to 3.3V to ensure that the module can work normally when the battery is lower than 3.3V;

4. USB power supply and 3.7V-4.2V battery power supply (this case uses a single 18650 power supply). When the USB is inserted, the battery is charging and the power supply switches to USB power supply;

5. Use the public version of the app to check temperature, humidity and battery power, with a low battery warning function;

6. Use the upper protective cover to press the micro switch. When the protective cover is removed, the app will alarm.

Tuya Smart Platform Process:

Tuya’s official website provides many detailed development documents and videos. This project attachment also has development documents for the SoC solution, please check it out!

Tuya SoC circuit reference diagram:

The Tuya Smart Platform is really great. The schematic diagram has been drawn for you. We only need to use EDA to draw the PCB and make it!

Physical and APP display pictures:

The picture below shows the Tuya Arduino temperature and humidity expansion board, debugging the program: Open source website

It’s a bit nervous to speak in a video for the first time. Many functions in the app are not displayed. When adding linkage, you can choose to turn on the air conditioner mode, temperature, wind speed, etc. I will re-record in the future.
