MQ-5 Natural/ LPG Gas Sensor Module

MQ-5 Natural/ LPG Gas Sensor Module for Arduino

Features

• Small sensitivity to LPG, H2, LPG, CH4, and CO
• Fast response
• Stable and long life
• Simple drive circuit
• Indication of the signal output
• Dual signal output (analog output, and TTL level output)
• TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
• Liquefied petroleum gas, natural gas, city gas, better sensitivity
• Has a long life and reliable stability

Specifications

• Working Voltage: 4.9V-5.1V
• Heater Resistance: 31±10%
• Adjustable Resistance
• Sensing Resistance Range: 10 – 60K
• Sensor Heat Consumption: 0.5-800mW
• Detecting Concentration: 200-10000ppm

Pinouts of MQ5 Sensor

• Pin Name
• Description
• Vcc - Power Pin requires an operating voltage of 5V
• GND - Ground pin
• DO - Digital out the pin, to get the digital output from the sensor, need to set the threshold value using Pot
• AO - Analog out the pin. It based the output of this pin on the intensity of the methane gas
