DO Output: TTL digital 0 and 1 (0.1 and 5 V); AO output: 0.1-0 0.3 V (based on the pollution), the maximum concentration of a voltage of about 4 V. Special Note: After the sensor is supplied with power, has to warm up around 20S measurement data was stable, thermal sensor is a normal phenomenon, because the internal heating wire when hot is not normal. MQ2 gas sensor in the clean air low conductance tin oxide (SnO2) used sensitive material. If it increases the environment in which the sensor for combustible gases, conductivity sensor mit increasing concentration of combustible gases in air. Using a simple circuit for converting the change of conductivity of the gas concentration corresponding to the output signal. Color: As shown Module Properties: With high-quality dual-panel design, with light and TTL signal output instructions; The switching signal with a DO (TTL) and analog output AO, TTL output valid signal is low. (Low-level signal off when the output light can be directly connected to the minicontroller or relay module) There are four Screw Holes for easy positioning; Dimensions: 32 (L) * 20 (W) * 15 (H) Chip: LM393, ZYMQ-2 gas sensors Detection of gas: combustible gases, vapors, Detectable concentrations: 300-10000ppm (flammable gas) Wiring: VCC: positive power supply (5 V) GND: Power supply is negative DO: TTL switching signal output AO: analog signal output Module Applications: Gas can be used in homes and factories Leakage monitoring device for the detection of gas, butane, propane, methane, smoke, etc.,.MQ2 gas sensor in the clean air low conductance tin oxide (SnO2) used sensitive material. Detection of gas: combustible gases, vapors. 1x MQ-2 Gas Sensor Module. With high-quality dual-panel design, with light and TTL signal output instructions; The switching signal with a DO (TTL) and analog output AO, TTL output valid signal is low.\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43035622834344,"sku":"U2I-1-323951135961","price":1290.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/s-l2000__89714_7bea0846-ba8c-4c8c-9080-05cca751ff0c.jpg?v=1672652283","url":"https:\/\/shop2india.com\/products\/mq2-gas-sensor-module-smoke-methane-butane-detection-300-10000ppm-for-ardui-e8m7","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
