Description: 1. The MQ-3 Gas Sensor Module is a versatile gas detection component designed to identify various hydrocarbon gases like Benzene, CH4 (Methane), Hexane, LPG (Liquified Petroleum Gas), and CO (Carbon Monoxide). 2. Design: It features a sensitive MQ-3 semiconductor sensor element encapsulated in a protective ceramic housing to ensure prolonged performance and resistance against external elements. 3. Operation: The module works on the principle of resistive gas sensing, with the resistance value of the sensor changing based on the presence or absence of target gases. 4. Versatility: This sensor module is widely used in various applications, including industrial process control systems, home automation projects, and portable gas detection devices. 5. Connectivity: The MQ-3 Gas Sensor Module can be easily integrated into different IoT platforms via analog inputs on microcontrollers or data loggers for real-time monitoring and analysis. 6. Detection range and sensitivity: This sensor c
