This article details a DIY digital barograph project that replaces traditional mechanical barographs with a modern digital solution using a BME280 pressure sensor, an ESP32 microcontroller, and a 128x64 LCD display. It offers advantages like eliminating paper replacement and reducing maintenance.
This article details a project to display sensor data (temperature, humidity, pressure, luminosity, date, time, and IP address) on an ESP32 CYD board using LVGL and a 2.8" TFT touchscreen. The project uses a BME280 sensor and a built-in LDR on the CYD board, retrieving the current date and time from the WorldTimeAPI via WiFi. It guides users through the necessary setup, including installing libraries (LVGL, TFT_eSPI, ArduinoJson, Adafruit BME280), configuring WiFi credentials, and wiring the BME280 sensor. The code creates a responsive table to display the data, with a refresh button for updates.
