The jOY-iT SEN-MQ4-V2 is an analog gas sensor module based on the MQ-2 sensing element, designed for the detection of combustible gases and smoke. It provides a proportional analog output signal that varies with gas concentration, making it suitable for integration into development boards and prototype setups.
Detects a wide range of combustible gases and smoke with high sensitivity
Analog output signal enables direct connection to microcontroller ADC inputs without additional conversion circuitry
Compact sensor board format fits standard breadboard and development board mounting
The MQ-2-based sensing element responds to multiple gas types simultaneously, including natural gas, methane, and liquefied petroleum gas. The analog output allows continuous concentration monitoring rather than a simple alarm threshold, which is essential for calibration and data logging in development environments.
Ideal für...
Electronics hobbyists, prototyping teams, and students working on gas detection or air quality monitoring projects. The module is suited for anyone building custom sensor arrays or integrating gas detection into a larger IoT or automation system.
Anwendung von SEN-MQ4-V2
Connect the analog output pin to a microcontroller ADC input (e.g., Arduino, ESP32, Raspberry Pi). Power the module with 5 V DC and read the voltage level to determine gas concentration relative to the baseline. For best results, allow a 24-hour warm-up period before taking measurements.
jOY-iT manufactures sensor modules and electronic components for maker and development applications. The brand focuses on gas sensing, environmental monitoring, and prototyping hardware. Products are distributed through Brack/Alltron in the Swiss market.
The MQ-2 sensing element detects combustible gases including natural gas, methane, liquefied petroleum gas (LPG), and smoke. The sensitivity curve is highest for methane and natural gas.
Connect the analog output pin to an ADC input on your microcontroller (e.g., Arduino, ESP32). Power the module with 5 V DC. The output voltage scales proportionally with gas concentration.
The module weighs approximately 0.007 kg (7 grams). The sensor board format is compact and compatible with standard breadboard mounting.
The delivery includes one jOY-iT SEN-MQ4-V2 gas sensor module. No additional cables or connectors are included.
The product comes with a 24-month manufacturer warranty covering material and manufacturing defects.
