MQ-7 Gas Sensor Module

MQ-7 Gas Sensor ModuleMQ-7 Gas Sensor Module is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 10 to 500ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.Sensitive material MQ-7 gas sensors used in clean air, low conductivity tin oxide (SnO2). High-low temperature cycling detection mode (1.5V heating) carbon monoxide detector, conductivity sensor with the increasing concentration of carbon monoxide gas in the air increases, high-temperature (5.0V heating) cleaning cryoadsorption stray gases. Using a simple circuit to change the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-7 gas sensor of high sensitivity for carbon monoxide, this sensor can detect a variety of gases containing carbon monoxide, is a low-cost sensors for a variety of applicationsApplication: Can be used for home and factory gas leakage monitoring devices, suitable for liquefied petroleum gas, butane, propane, methane, smoke, etc. General SpecificationOperating voltage (v)DC 5Range10 ~ 1000 ppmCharacteristic gas100 ppm COSensitivity≥ 3%.Return time≤ 30 secHeating resistance± 31 ΩHeating current≤ 180 mAHeating voltage5.0V ± 2V / 1.5 ± 1VHeating powerapprox. 350 mWAmbient temperature (°C)-20 ~ 50Humidity≤ 95% RHOxygen content21%.Length (mm)35Width (mm)20Height (mm)11Related video  here  To check out our website for different types of sensors, click SensorsWhat are MQ sensors?MQ gas sensors are a family of sensors which are used to detect a wide variety of gases like alcohol, smoke, methane, LPG, hydrogen, NH3, Benzene, Propane etc. These sensors are made up of electrode which is coated with a sensing material, and it is heated to make it more reactive and sensitive.What does MQ stand for in gas sensor?MQ – 214 is a Methane (CH4) gas sensor detects the concentrations of methane in the air and outputs its reading as an analog voltage. Keep an eye on our website to avail the –MQ-7 Gas Sensor Module best price in BD (Bangladesh)
