-This project is designed to display CO2 levels using a [Panel ESP32-4848S040](https://homeding.github.io/boards/esp32s3/panel-4848S040.htm).<br>
-It reads data from a Senseair S8 CO2 sensor and an SHT31 temperature and humidity sensor, displaying the real-time readings.
+This is a [PlatformIO](https://platformio.org/) project designed to display CO<sub>2</sub> levels using a [Panel ESP32-4848S040](https://homeding.github.io/boards/esp32s3/panel-4848S040.htm).<br>
+It reads data from a Senseair S8 CO<sub>2</sub> sensor and an SHT31 temperature and humidity sensor, displaying the real-time readings and the history of the last 2 hours.
 
-Sensors are on separate sensor board and are read over websocket.<br>
-This setup is chosen because the CO2 sensor uses over 300mA when reading and this made the tft screen flicker during the reading.<br>
