The sensor can measure concentrations of 10 to 10,000 ppm. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.\u003c\/p\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eThis module provides both digital and analog outputs. The threshold level for digital output can be easily adjusted using the preset on the board. The MQ-7 sensor module can be easily interfaced with Micro-controllers, Arduino, etc.\u003c\/div\u003e\n\u003ch3\u003eStandard test conditions :\u003c\/h3\u003e\n\u003cp\u003eTemperature: 20 degree ± 2 degree\u003cbr\u003e\nHumidity: 65% ± 5% RH\u003cbr\u003e\nStandard test circuit: Vc: 5.0V ± 0.1V; Vh(high):5.0V±0.1V\u003cbr\u003e\nVh(low):1.5V±0.1V\u003c\/p\u003e\n\u003ch3\u003eElectrical properties:\u003c\/h3\u003e\n\u003cp\u003eInput voltage: DC5V power (current): 150mA\u003cbr\u003e\nDO output: TTL digital 0 and 1 (0.1 and 5V)\u003cbr\u003e\nAO output :0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V\u003c\/p\u003e\n\u003ch2\u003eSpecifications and Features:\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eOperating voltage : DC 5 V.\u003c\/li\u003e\n\u003cli\u003eIC driver: LM 393.\u003c\/li\u003e\n\u003cli\u003eSize : 11 x 33 x 20 mm.\u003c\/li\u003e\n\u003cli\u003eRange: 10 to 1000 ppm.\u003c\/li\u003e\n\u003cli\u003eCharacteristic gas: 100 ppm CO.\u003c\/li\u003e\n\u003cli\u003eSensitive resistance: 2 to 20 10kohm 10kohm at 100ppm CO.\u003c\/li\u003e\n\u003cli\u003eSensitivity : ≥ 3%.\u003c\/li\u003e\n\u003cli\u003eReturn time: ≤ 30 s.\u003c\/li\u003e\n\u003cli\u003eHeating resistance: ± 31ohm 3ohm.\u003c\/li\u003e\n\u003cli\u003eHeating current: ≤ 180 mA.\u003c\/li\u003e\n\u003cli\u003eReaction time: ≤ 1 s.\u003c\/li\u003e\n\u003cli\u003eHeating voltage : 5.0V ± 2V \/ 1.5 ± 1V.\u003c\/li\u003e\n\u003cli\u003eHeating power: approx. 350 mW.\u003c\/li\u003e\n\u003cli\u003eAmbient temperature : -20 ° C to + 50 ° C.\u003c\/li\u003e\n\u003cli\u003eHumidity: ≤ 95% RH.\u003c\/li\u003e\n\u003cli\u003eOxygen content: 21%.\u003c\/li\u003e\n\u003cli\u003eThe analog output voltage, the higher the concentration the higher the voltage.\u003c\/li\u003e\n\u003cli\u003eThe carbon monoxide detection with better sensitivity.\u003c\/li\u003e\n\u003cli\u003eThere are four screw holes for easy positioning;\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions: 32 x 20 x 22 mm (LxWxH)\u003c\/li\u003e\n\u003cli\u003eWith a long service life and reliable stability\u003c\/li\u003e\n\u003cli\u003eRapid response and recovery characteristics\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eAttachments and Links :\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eMQ-7 Datasheet:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003ePackage Includes :\u003c\/h2\u003e\n\u003cp\u003e1 x MQ7 CO Carbon Monoxide Coal Gas Sensor\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Electronics Hub","offers":[{"title":"Default Title","offer_id":54466816508217,"sku":"product-6376","price":260.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/mq7_sensor-1.webp?v=1789235064","url":"https:\/\/electronicshub.pk\/products\/mq7-co-carbon-monoxide-coal-gas-sensor","provider":"Electronics Hub","version":"1.0","type":"link"}
