Description: 1. Sensors: The MQ-9 Gas Sensor Module is a versatile gas detector that can detect carbon monoxide (CO), methane (CH4), and Liquified Petroleum Gas (LPG) through the utilization of an MQ-9 sensor chip. 2. Digital Output: This module offers a digital output signal, which is more reliable and precise compared to analog alternatives. It enables easier integration with various IoT systems and microcontrollers for efficient data processing. 3. User-friendly Design: Featuring an intuitive design, this gas sensor module comes pre-assembled with the MQ-9 sensor chip, a heater, and necessary resistors. This simplifies setup, making it suitable for hobbyists and professionals alike. 4. Heating Element: A built-in heating element ensures optimal performance by keeping the MQ-9 sensor at an optimal temperature of around 350°F (177°C). This enhances sensitivity to gas molecules and minimizes potential false readings in cold environments. 5. LED Indicator: The module includes an LED indicator t
