The resistance of the test element changes with the variation of electrical and thermal conductivity caused by the adsorption of flammable gas on the surface of the sensitive material, thereby measuring the gas concentration. The MR007 detection circuit adopts a Wheatstone bridge, which consists of a pair of detection elements and compensation elements as one arm of the bridge. When encountering flammable gas, the resistance of the detection element decreases, and the output voltage of the bridge changes. This voltage change increases with the increase of gas concentration. The compensation element serves as a reference and temperature compensation.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003e\u003cspan

Oxidation-reduction reaction with carbon monoxide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of carbon monoxide. So the concentration of the target gas could be got by measuring the value of current. The 4th electrode (auxiliary electrode) is used to compensate the zero current, to make it has the characteristics of strong signal level and low zero current.\u003c\/p\u003e\n\u003ch4

When combustible gases are present in the sensor's environment, the conductivity of the sensor increases with the concentration of the combustible gas in the air. Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the gas concentration. The MO gas sensor exhibits high sensitivity to sensitive gases such as liquefied petroleum gas, propane, and hydrogen, and is also ideal for detecting natural gas and other combustible vapors. This sensor can detect a variety of combustible gases and is a low-cost sensor suitable for a wide range of applications.\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-size:20px;\"\u003eComponent external structure\u003cbr\u003e \u003cimg cke-id=\"img44\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae01.alicdn.com\/kf\/S6148b5a5da21441fa0caf9c01c7bc7fd9.jpg?width=1000\u0026amp;height=411\u0026amp;hash=1411\" style=\"width: 1000px; height: 411px;\"\u003e\u003cimg cke-id=\"img45\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae01.alicdn.com\/kf\/S7b210f016e2d44638a1b17d4187a6b0aw.jpg?width=1000\u0026amp;height=1000\u0026amp;hash=2000\"\u003e\u003c\/span\u003e\n\u003c\/h1\u003e \n\u003ch1 style='font: 700 24px \/ 34px quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, Oxygen, Ubuntu, Cantarell, \"Open Sans\", \"Helvetica Neue\", sans-serif; margin-top: 0px !important; margin-right: 0px; margin-bottom: 16px; margin-left: 0px; color: rgb(15, 17, 21); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'\u003eProduct Features\u003cbr\u003e \u003cspan style=\"font-size:18px;\"\u003e1.Utilizes a high-quality double-sided board design with power indication and TTL signal output indication.\u003cbr\u003e 2.Features both DO switch signal (TTL) output and A0 analog signal output.\u003cbr\u003e 3.The TTL output active signal is low level (the signal light turns on when the output is low, and it can be directly connected to a microcontroller or relay module).\u003cbr\u003e 4.The analog output voltage increases with higher gas concentration.\u003cbr\u003e 5.Exhibits high sensitivity to methane and natural gas detection.\u003cbr\u003e 6.Equipped with four screw holes for easy positioning.\u003cbr\u003e 7.Product dimensions: 32 (L) × 20 (W) × 22 (H) mm.\u003cbr\u003e 8.Offers long service life and reliable stability.\u003cbr\u003e 9.Provides fast response and recovery characteristics.\u003c\/span\u003e\n\u003c\/h1\u003e \n\u003ch1 style='font-weight: 600; font-size: 27.432px; line-height: 1.5; margin: 18.288px 0px 13.716px; color: rgb(64, 64, 64); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, \"Noto Sans\", Ubuntu, Cantarell, \"Helvetica Neue\", Oxygen, \"Open Sans\", sans-serif; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'\u003e\u003cimg cke-id=\"img46\" referrerpolicy=\"no-referrer\" src=\"https:\/\/ae01.alicdn.com\/kf\/S25953da5a91646c3b6b73c88d37a44b7Q.jpg?width=1000\u0026amp;height=1000\u0026amp;hash=2000\" style=\"width: 1000px; height: 1000px;\"\u003e\u003c\/h1\u003e \n\u003ch1 style='font: 700 24px \/ 34px quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, Oxygen, Ubuntu, Cantarell, \"Open Sans\", \"Helvetica Neue\", sans-serif; margin-top: 0px !important; margin-right: 0px; margin-bottom: 16px; margin-left: 0px; color: rgb(15, 17, 21); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'\u003eProduct Performance\u003cbr\u003e \u003cspan style=\"font-size:16px;\"\u003eInput Voltage: DC 5V\u003cbr\u003e Power Consumption (Current): 150 mA\u003cbr\u003e DO Output: TTL Digital Signals 0 and 1 (0.1 V and 5 V)\u003cbr\u003e AO Output: 0.1–0.3 V (relative to no pollution), approximately 4 V at high concentration\u003c\/span\u003e\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-size:16px;\"\u003eFriendly Reminder: After the sensor is powered on, it requires a warm-up period of about 1 minute for the measurement data to stabilize.

A heater and a metal oxide semiconductor gas-sensitive layer are fabricated on both sides of a miniature Al2O3 ceramic substrate, respectively, and packaged in a metal casing. When the detected gas is present in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert this change in conductivity into an output signal corresponding to the gas concentration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv

above figure is the basic test circuit of MP503 sensor. The sensor requires two voltages: heater voltage (VH) and test voltage (VC). Among them, VH is used to provide a specific working temperature for the sensor, and DC or AC power can be used. VRL is the voltage across the load resistance (RL) of the sensor in series. VC is the test voltage for the load resistance RL. A DC power supply is required.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align:center\" align=\"center\"\u003e\n\u003cp\u003e\u003cimg style=\"width:1000px\" width=\"1000px\" src=\"https:\/\/ae01.alicdn.com\/kf\/S7671a5ed6b56414daf33468ed6482b80Q.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width:1000px\" width=\"1000px\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sc14aed7ec9a045de9752b8734dbc3b5et.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width:1000px\" width=\"1000px\" src=\"https:\/\/ae01.alicdn.com\/kf\/S512e70965ecf4fa6ba955a41648ae3d08.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"Default Title","offer_id":55440979427627,"sku":"\u003cnone\u003e","price":11.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/S7671a5ed6b56414daf33468ed6482b80Q.webp?v=1788748247"},{"product_id":"keyestudio-mq-series-sensor-gas-sensor-mq-2-mq-3-mq-5-mq-135-mq-6-mq-8-mq-7-module-for-arduino-sensor-diy-electronic-projec","title":"Keyestudio MQ Series Sensor Gas Sensor MQ-2 MQ-3  MQ-5 MQ-135  MQ-6 MQ-8  MQ-7 Module  for Arduino Sensor DIY Electronic Projec","description":"\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\u003cp\u003e\u003cspan\u003eBrand Name\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003ekeyestudio\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eChoice\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eyes\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eHigh-concerned chemical\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003enone\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eOrigin\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eMainland China\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eOutput\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eAnalog Sensor\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eTheory\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eGas Sensor Module\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eType\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eGas Sensor\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eUse\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eGas Sensor\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003eis_customized\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eYes\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style='font-size:18px;font-family:\"times new roman\", times, serif'\u003eThis analog gas sensor - MQ2 is used in gas leakage detecting equipment in consumer electronics and industrial markets.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style='font-size:18px;font-family:\"times new roman\", times, serif'\u003eThis sensor is suitable for detecting LPG, I-butane, propane, methane, alcohol, Hydrogen and smoke.
