If you like this project, please give me a boost! Every bit of your support motivates me to continue refining cooler smart hardware. Thank you all!
🚀 Project Introduction
This is a high-end desktop environment monitoring station developed based on ESP32-S3. It can not only monitor indoor temperature, humidity, and PM1.0 / PM2.5 / PM10 particulate matter concentration in real-time through local sensors, but also retrieve outdoor weather and temperature by linking with Home Assistant via ESPHome
The project is equipped with a 3.5-inch large screen and capacitive touch, supporting dual-page interaction, and has a built-in 18650 lithium battery, making it a smart home hardware that combines aesthetics and functionality
✨ Main Features
- Dual page display: seamlessly switch between "Indoor Environment" and "Clock Weather" pages by tapping the screen
- High-precision monitoring: uses AHT20 temperature and humidity sensor and Plantower PMSX003 laser particulate matter sensor
- HA deep linkage: automatically synchronizes outdoor sensor data and weather forecasts from Home Assistant
- Ultra-smooth UI: based on mipi_spi driver and 40MHz SPI frequency, providing a smooth visual refresh
- Portable with lithium battery: equipped with 18650 lithium battery and 5V/2.4A charge/discharge protection module, supports charging while in use
- Full Chinese support: perfectly supports Source Han Sans Chinese display, localizing weekdays and dates
🛠️ Hardware List (BOM)
- Controller: ESP32-S3-DevKitC-1 (16MB Flash)
- Display screen: 3.5-inch TFT screen (Driver chip ST7796, 480x320)
- Touch layer: Capacitive touch (Driver chip FT63x6)
- Sensors:
- Temperature & Humidity: AHT20 (I2C)
- Particulate Matter: Plantower PMSX003 (UART)
- Power management:
- Battery: 18650 lithium battery (3000mAh+)
- Module: 5V 2A/2.4A charge/discharge integrated module (supports overcharge and over-discharge protection)
- Enclosure: recommended 3D Printed
🚀 Advanced Play:
If you are pursuing the ultimate data experience, it is recommended to replace the AHT20 module with SCD41. It uses non-dispersive infrared technology to accurately measure CO2 concentration. Wiring also uses the I2C bus (GPIO4/5), and you only need to enable the scd4x platform in the code, making it the ultimate choice for high-end environmental stations
