The gas sensing material used in the MQ-7 gas sensor is tin dioxide (SnO2) with lower conductivity in clean air. The low-temperature (1.5V heating) is used to detect carbon monoxide by high-temperature cycle detection method. The conductivity of the sensor increases with the increase of the concentration of carbon monoxide gas in the air, and the high-temperature (5.0V heating) cleans the stray gas adsorbed at low temperature. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e \u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e\u003cspan style=\"box-sizing:border-box;font-size:16px;max-width:100%;margin:0px;padding:0px;\"\u003e\u003cspan style='box-sizing:border-box;max-width:100%;font-family:\"margin:0px;padding:0px;'\u003e        The MQ-7 gas sensor is highly sensitive to carbon monoxide.

The gas sensing material used in the MQ-7 gas sensor is tin dioxide (SnO2) with lower conductivity in clean air. The low-temperature (1.5V heating) is used to detect carbon monoxide by high-temperature cycle detection method. The conductivity of the sensor increases with the increase of the concentration of carbon monoxide gas in the air, and the high-temperature (5.0V heating) cleans the stray gas adsorbed at low temperature. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e \u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e\u003cspan style=\"box-sizing:border-box;font-size:16px;max-width:100%;margin:0px;padding:0px;\"\u003e\u003cspan style='box-sizing:border-box;max-width:100%;font-family:\"margin:0px;padding:0px;'\u003e        The MQ-7 gas sensor is highly sensitive to carbon monoxide.

The gas sensing material used in the MQ-7 gas sensor is tin dioxide (SnO2) with lower conductivity in clean air. The low-temperature (1.5V heating) is used to detect carbon monoxide by high-temperature cycle detection method. The conductivity of the sensor increases with the increase of the concentration of carbon monoxide gas in the air, and the high-temperature (5.0V heating) cleans the stray gas adsorbed at low temperature. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e \u003c\/div\u003e\n\u003cdiv style='box-sizing:content-box;font-size:14px;font-family:\"white-space:normal;word-spacing:0px;text-transform:none;font-weight:400;color:#000000;font-style:normal;orphans:2;widows:2;margin:0px;letter-spacing:normal;background-color:#FFFFFF;text-indent:0px;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;text-decoration-thickness:initial;padding:0px;'\u003e\u003cspan style=\"box-sizing:border-box;font-size:16px;max-width:100%;margin:0px;padding:0px;\"\u003e\u003cspan style='box-sizing:border-box;max-width:100%;font-family:\"margin:0px;padding:0px;'\u003e        The MQ-7 gas sensor is highly sensitive to carbon monoxide.

style=\"font-size:28px;\"\u003eThe gas sensitive material used in the MQ131 ozone gas sensor is tin dioxide (Sn02), which has a low conductivity in clean air. When ozone gas is present in the environment of the sensor, the conductivity of the sensor increases with the increase of the concentration of ozone gas in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas. MQ131 Ozone gas sensor has high sensitivity to ozone, strong oxidizing gases such as chlorine and nitrogen dioxide also have a certain sensitivity, and organic interference gases react in the opposite direction to ozone.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:28px;\"\u003eApplication fields: household ozone concentration alarm, industrial, ozone concentration alarm, portable

A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas.

When there is flammable gas in the environment where the sensor is located, the conductivity of the sensor varies with the concentration of flammable gas in the air. Increased and increased, it is suitable for household or industrial detection devices for gas, natural gas and liquefied gas, and has excellent resistance to ethanol and smoke interference. It is an economical sensor suitable for a variety of applications. C002 is a three-tone optional alarm sound voice chip, which internally stores the sound of police car 110, fire alarm 119 and ambulance 120. The external oscillating resistor is lOOK ~ 240Kohm (the higher the resistance, the slower the sound speed), it can be driven after power-on. The buzzer sounds. 1 pin grounding, 2 pin output, 3 pin selection sound terminal, 4 feet connected to the positive pole of the power supply, 5 and 6 feet connected to the oscillation resistor. The gas detection and alarm circuit uses the alarm sound of the fire alarm 119, and its working voltage is generally 2.4 to 3.6V.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S74ddfb2fceb74d2999cacc03ccf82b8aE.jpg\"

When there is combustible gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of combustible gas in the air increases. A simple circuit can be used to convert changes in conductivity into an output signal corresponding to that gas concentration. The MQ-6 gas sensor has high sensitivity to propane and liquefied petroleum gas, and also has good sensitivity to natural gas. This sensor can detect a variety of flammable gases and is a low-cost sensor suitable for a variety of applications.\u003cbr\u003e\r\n\u003cbr\u003e\r\nModule application:\u003cbr\u003e\r\nSuitable for household or industrial detection devices for LPG (liquefied petroleum gas), propane, and LNG (liquefied natural gas).

When ozone gas is present in the environment of the sensor, the conductivity of the sensor increases with the increase of the concentration of ozone gas in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas. MQ131 Ozone gas sensor has high sensitivity to ozone, strong oxidizing gases such as chlorine and nitrogen dioxide also have a certain sensitivity, and organic interference gases react in the opposite direction to ozone.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:28px;\"\u003eApplication fields: household ozone concentration alarm, industrial, ozone concentration alarm, portable ozone concentration detector.\u003c\/span\u003e\u003c\/span\u003e\u003c\/h1\u003e\n\u003ch1\u003e?\u003c\/h1\u003e\n\u003ch1\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cspan style=\"font-size:28px;\"\u003e??

When there is sensitive gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the concentration of combustible gas in the air. There are different resistance values for different concentrations, and a simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. The MQ-8 gas sensor has high sensitivity to hydrogen and is ideal for monitoring other hydrogen-containing gases. This sensor can detect a variety of hydrogen-containing gases, especially city gas. It is a low-cost sensor suitable for a variety of applications and is suitable for hydrogen leakage monitoring devices in households or industries. Can not be interfered by ethanol vapor, oil fume, carbon monoxide and other gases. The sensor is specially equipped with M3 fixed mounting hole, using wide voltage LM393 comparator, clean signal, good waveform, strong driving ability, more than 15mA, with adjustable precision

When there is combustible gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of combustible gas in the air increases. A simple circuit can be used to convert changes in conductivity into an output signal corresponding to that gas concentration. The MQ-6 gas sensor has high sensitivity to propane and liquefied petroleum gas, and also has good sensitivity to natural gas. This sensor can detect a variety of flammable gases and is a low-cost sensor suitable for a variety of applications.\u003cbr\u003e\r\n\u003cbr\u003e\r\nModule application:\u003cbr\u003e\r\nSuitable for household or industrial detection devices for LPG (liquefied petroleum gas), propane, and LNG (liquefied natural gas).
