When there is a polluting gas in the\nenvironment, the conductivity in the sensor increases with the concentration\nof polluted gas in the air. The change in conductivity can be converted to an\noutput signal corresponding to the gas concentration using a simple circuit.\nSpecifications: Size:32 20 22mm (LWH) Input voltage: DC5V Power\nconsumption ( current ): 150mA DO output: TTL digital 0 and 1 ( 0.1 and 5V) AO\noutput :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a\nvoltage of about 4V Note: After the sensor is powered , needs to warm up\naround 20S, measured data was stable, heat sensor is a normal phenomenon ,\nbecause the internal heating wire , if hot is not normal. The installation of\nelectronic modules requires basic knowledge and requires a certain electronic\nprofessional foundation and hands-on ability. Please purchase carefully!\nManual measurement, with small error. Please check size in detail before\npurchase. Real colors may slightly differ from the pictures, as it depends on\nspecific monitor settings and light brightness. We highly appreciate all\ncustomers opinions to improve the selling, also if anything you unsatisfied,\nplease contact us for probable best solution.
