MQ-9 Carbon Monoxide, Combustible Gas Sensor Module

Product Description Gas sensor MQ9 detects the presence of CO (Carbon Monoxide), CH4 (Methane) and LPG in the air. The best results are given while compounds are in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly. Key features Detects : CO(Carbon Monoxide), CH4(Methane), LPG Voltage : 5V Digital(HIGH/LOW) and analog(0V-5V) output With LM393 comparator Comes with soldered 4-pin male header Dimensions : 32 x 22 x 27 mm / 1.3″ x 0.9″ x 1.1″ Package Includes: 1x MQ-9 Carbon Monoxide, Combustible Gas Sensor Module Relate Products: Sensors | Modules
