MQ2 Gas Sensor Module Smoke Methane Butane Detection

Key Features:

• Wide Detection Range: Capable of detecting gas concentrations from 200 to 10,000 parts per million (ppm), making it suitable for various environments.

• Dual Output: Provides both analog and digital outputs. The analog output offers a voltage range of 0-5V corresponding to gas concentration levels, while the digital output provides a TTL signal (0 or 5V) for threshold-based detection.
• Adjustable Sensitivity: Features a built-in potentiometer to adjust the digital output threshold, allowing customization based on specific application requirements.
• Low Power Consumption: Operates at 5V with a current consumption of approximately 150mA, making it suitable for battery-powered applications.
• Fast Response Time: Offers a quick response to gas presence, enhancing the reliability of detection systems.
