Description:
The MQ-9 Gas Sensor Module is an efficient and affordable solution for detecting Carbon Monoxide (CO), Methane (CH4), and LPG (Liquefied Petroleum Gas) in various environments. The sensor uses a sensitive SnO2 material to detect these gases with high accuracy. This module offers both analog and TTL digital output, allowing you to integrate it easily into your safety and monitoring projects. The sensor operates at different temperatures to detect CO at low temperature and Methane, Propane, and other combustible gases at high temperature.
Versatile Gas Detection: Senses Carbon Monoxide (CO), Methane (CH4), LPG, and other combustible gases.
High Sensitivity: Highly sensitive to both CO and combustible gases like Methane, Propane, and LPG.
Long Life: The sensor is built for longevity and low-cost operation.
Simple Integration: Easy-to-use with a simple drive circuit for both analog and digital output.
Temperature-Based Detection: Detects CO at low temperature (heated by 1.5V) and combustible gases at high temperature (heated by 5V).
Applications: Ideal for both domestic and industrial gas leakage detection systems, as well as portable gas detectors.
Operating Voltage: 5V DC
Output Type: Digital (DO) and Analog (AO)
Material: Tin Oxide (SnO2)
Sensitivity: High sensitivity to CO and combustible gases (Methane, Propane, LPG)
Temperature-Dependent Detection: Low temperature for CO detection and high temperature for Methane, Propane, and LPG detection.
VCC: Positive pole (5V)
GND: Negative pole
DO: TTL switch signal output (digital)
AO: Analog signal output
Gas Leak Detection: Suitable for domestic and industrial gas leakage detectors.
Portable Gas Detectors: Ideal for portable gas detection equipment for emergency and safety measures.
Safety Systems: Used in safety applications to monitor gas levels in various environments.
