Nextion+Arduino Temperature & Humidity Sensor

Hardware you need:

• Arduino Uno
• Nextion NX3224T024
• SHT1x (I've used this)
• Micro SD (I've used 1 GB and it is more than enough)
• Any Card reader

Dependences

• SHT1x library
• Nextion library
• Nextion ITEADLIB
• SoftwareSerial

Instruction

Before

Make sure you've already installed Arduino IDE

1. Download this repo and all libraries above
2. Upload the sketch to your microcontroller

I recommend using my firmware from this repo, but if you need to change the background for example, you need to have Nextion Editor. Skip to 5 step if you needn't

3. Open firmwarePattern.HMI in Nextion Editor and change all you need

4. Save your project as .tft

5. Open the SD card and make sure that it is empty

6. Drag and drop firmware.tft (firmwarePattern.tft if you did 4-5 steps)

7. Eject SD card

8. Assemble the device according to this scheme

9. Insert the SD card into the monitor tray and connect the device to a power source

10. Wait ~10 seconds to this screen

11. Eject SD card and reconnect the device

12. Profit
