The JE MQ-2 Gas Sensor Module is a compact gas-detection and sensing board designed for detecting the presence of smoke and combustible gases. It is suitable for embedded-system learning, prototyping, IoT projects, and basic gas-monitoring applications.
The module provides an analog output that can be read by a microcontroller or development board, along with a digital threshold output on typical module configurations.
Key Features:
- Sensor: MQ-2 semiconductor gas sensor
- Detection: Smoke and combustible gases
- Outputs: Analog output and digital threshold output
- Interface: Simple GPIO/ADC interface
- Adjustable Threshold: Onboard potentiometer for digital-output sensitivity
- Indicator: Status LED for digital output
- Compatible Platforms: Arduino, ESP32, STM32, Nuvoton and other microcontrollers
- JE Platform: Designed for the Just Embedded (JE) development-board ecosystem
Applications:
Gas and smoke detection experiments, IoT sensor nodes, home-automation projects, safety-system prototypes, embedded-system learning, environmental monitoring and industrial sensing demonstrations.
