MQ-9 Carbon Monoxide CO Methane LPG Gas Detector Module

This MQ-9 sensor module is a simple to use carbon monoxide (CO) and combustible gas (Methane (CH4), LPG) sensor, suitable for detecting CO, methane and LPG gas concentrations in the air. The MQ-9 can detect CO gas concentrations anywhere from 10 to 1000ppm and combustible gasses from 100-10000ppm. Suitable for home and industrial use, it has fast response and recovery characteristics, long life and reliable stability.

The module features dual signal outputs: An analog output (0V to ~5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer.

Specifications:

• Operating voltage: 5 Volts DC (VCC Pin) 
• Maximum power consumption: 800mW (160mA at 5V)
• Dual signal output (analog (AO pin) and TTL (DO pin) level output)
• TTL output signal is normally low, goes high when has is detected. Threshold is adjusted with the onboard potentiometer
• 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
