In this guide, we will learn how to use DWIN HMI LCD Display with ESP32 WiFi Module. Currently, DWIN HMI Displays are very popular in the Makerโ€™s market. Using the DGUS Software we can design any UI and control the UI Content with a microcontroller. The 7-inch DMG80480C070 Display has a resolution of 800X480 pixels. We can interface the display with any with 5V compatible microcontroller board like Arduino, ESP8266, ESP32, PIC, 8051, STM32, etc.

For this demo, we will make a Smart Home Controller using DWIN HMI Display & ESP32 Module. The BME280 will read the temperature, humidity, pressure, and dew point and display the data on DWIN Screen. Similarly, we will also control a 4-channel Relay Module using the UI/widgets on DWIN Screen.

The Smart Home Controller Project using DWIN HMI Display & ESP32 uses a 7-inch DWIN LCD Display DMG80480C070 and other components. The project comprises the following steps:

1. Installing required Software & Tools
2. Designing the GUI of the Display
3. Upload project files to the Display
4. Interface sensor and relays to the ESP32
5. Make a UART communication between ESP32 & DWIN HMI Display
6. Monitor sensor data & Control AC Home appliances from this touch display
