Description: 1. The MQ-4 Natural Gas Sensor is a methane gas detection module designed for use in various IoT applications. It specifically detects methane gas, which is the primary component of Compressed Natural Gas (CNG). 2. Key Features: - High sensitivity and accuracy with a detection range of 0-10,000ppm. - An electrochemical sensor that generates an electrical output proportional to the concentration of methane present in the environment. - Operating voltage of 5V DC with a current consumption of approximately 23mA. 3. Applications: Ideal for gas leakage detection systems, CNG refueling stations, industrial safety systems, and environmental monitoring projects. It can be integrated into various IoT platforms to send alerts or trigger actions based on gas concentration levels. 4. Easy-to-use: Comes with a screw terminal connection, enabling simple installation and wiring in different projects. The sensor output is analog voltage (0-5V), which can be read by microcontrollers like Arduino o
