A gas sensor is a device which detects the presence of gas in an area.This sensor interacts with a gas to measure its concentration. Each gas has a unique breakdown voltage i.e. the electric field at which it is ionized. Sensor identifies gases by measuring these voltages. The concentration of the gas can be determined by measuring the current discharge in the device.The MQ5 gas sensor detects the presence of various gases such as hydrogen, carbon monoxide, methane and LPG ranging from 100ppm to 3,000ppm. Specifications: Supply Voltage: 5V Detecting concentration :200-10000ppm LPG,LNG,Natural gas,Iso-butane Analog and Digital Output Digital Out is High or Low based on a adjustable preset threshold..
Sensitive for LPG, natural gas, coal gas
Output voltage boosts along with the concentration of the measured gases increases
Fast response and recovery
