ESP32 IoT Mini TV

Overview

1. Hardware Design
1.1 Core Board Selection:

ESP32-S3-WROOM-1-N16R8: Serves as the main controller, responsible for data processing, wireless communication, and power management.

1.2 Sensor Selection

: TVOC sensor (e.g., CCS811);
Temperature and humidity sensor (e.g., DHT40).

1.3 Display:

2.8-inch capacitive touchscreen: Connected via SPI or I2C interface .

1.4 Power Supply System

: Type-C interface for direct power supply.

1.5 Circuit Design

: Design the PCB board, allocate I/O ports appropriately, and ensure correct connection of each sensor, display, power management module, etc.
Pay special attention to the ESP32's GPIO allocation to avoid conflicts.

2. Software Design
2.1 ESP32 Firmware Development

Environment Setup: Develop using ESP-IDF or Arduino IDE.
Sensor Drivers: Write or integrate driver code for each sensor to read data.
