MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module
Presenting our MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module, a versatile tool crafted to identify compressed natural gas (CNG), methane (CH4), and various other gases in the environment.
This module is outfitted with an MQ-4 sensor and includes a standard 4 x 0.1″ header pin interface, providing both analog and digital outputs. The analog output changes with the gas concentration, while the digital output is activated when the gas concentration surpasses a predetermined threshold, which can be adjusted using the onboard potentiometer. An LED indicator also notifies users of gas detection events.
Designed to operate with a 5V power supply, this module is well-suited for use with microcontrollers and other electronic circuits. The digital output facilitates easy integration into different systems, and the analog output allows for extensive sensor readings when connected to a microcontroller’s ADC.
Capable of detecting natural gas concentrations from 200 to 10,000ppm, our MQ-4 Sensor Module is perfectly suited for tasks that demand precise gas detection, especially in settings where methane (CH4) is common.
