This project logs data from an MQ2 gas sensor connected to an ESP32 to Google Sheets. The ESP32 connects to WiFi, reads the gas sensor values, and sends them to a specified Google Apps Script URL, ...

The MQ2 sensor measures the presence of gases in the environment, which the ESP32 reads and sends to Google Sheets for logging and monitoring. This project can be used for applications like gas ...

MQ-2 gas sensor can not only detect gas or smoke, but can also detect LPG, Alcohol, Propane, Hydrogen, Methane, and Carbon Monoxide.For interfacing, we are using the 5V and GND pin of the Arduino UNO ...

LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and gas sensors ...
