to detect gas leakage and trigger alerts. It can also send notifications using Wi-Fi (ESP8266/ESP32) or GSM. Key Components Arduino Uno/Nano – Main controller Gas Sensor (MQ-2, MQ-5, MQ-135) – Detects ...

In this project, an Arduino microcontroller is employed in conjunction with an MQ-2 gas detector sensor. The system is designed to monitor gas levels, and a specific threshold is predefined. When the ...

LPG (liquid petroleum gas) used in kitchen gas cylinders is a mixture of propane and butane in diverse compositions. Even though LPG is essential for use in kitchens and the public is usually alert ...

A Gas Leakage Detection System is designed, utilizing an Arduino Uno to solve this problem. In order to monitor and identify the presence of potentially dangerous gases like methane, propane, and ...

Arduino Uno is an open-source ... also known as Chemi-resistor as the detection is based upon a change of resistance of the sensing material when the gas comes in contact with the material. Using a ...

Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs ... We can also build it by using LM358 or LM393 and MQ3. As shown in the schematic diagram above, it contains ...
