Formaldehyde Detector
Formaldehyde detectorProject Overview
The formaldehyde detector: This project is made using an ESP32 board, a formaldehyde sensor, and an LCD color screen. The formaldehyde sensor is responsible for detecting the concentration of formaldehyde and TVOC values in the air, as well as the concentration of carbon dioxide. The ESP32 handles data processing, while the LCD screen displays the detected values.
