When the sensor is kept in their environment In the polluting\r\ngases , the conductivity sensor with increasing air pollution in gas\r\nconcentration increases. Using a simple circuit can change the conductivity\r\nConversion of an output signal corresponding to the gas concentration . MQ135\r\nsensor for ammonia, sulfide , benzene vapor high sensitivity of the smoke and\r\nother harmful monitor is also very good. This sensor can be seized Measure a\r\nvariety of harmful gases , is a low-cost sensors for a variety of applications\r\n.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n  \u003cul class=\"a\"\u003e\r\n         \u003cli\u003eMQ-135 Ammonia , Sulfide, Benzene Vapor Gas Sensor\u003c\/li\u003e\r\n         \u003cli\u003eInput Voltage : DC5V \u0026amp; Power consumption ( current ): 150mA \u0026amp; DO output: TTL digital 0 and 1 ( 0.1 and 5V) \u0026amp; AO output:0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V\u003c\/li\u003e\r\n         \u003cli\u003eSpecial note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .\u003c\/li\u003e\r\n         \u003cli\u003eSize: 32(L)x20(W)x22(H)mm\/1.26\"x0.79\"x0.76\"\u003c\/li\u003e\r\n         \u003cli\u003ePackage Include: 2PCS MQ-135 Sensor Module\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"HUABAN","offers":[{"title":"Default Title","offer_id":44154119127220,"sku":"B07875Y7HW","price":93.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B07875Y7HW.jpg?v=1775785952","url":"https:\/\/auspowers.com\/products\/2-pack-mq-135-air-quality-and-hazardous-gas-detection-sensor-alarm-module","provider":"AusPower Australia","version":"1.0","type":"link"}
