At its core is tin dioxide (SnO₂), a material with low conductivity in clean air. But when flammable gas is present? The conductivity goes up—letting you quickly detect changes in gas concentration.\nThis sensor is a great fit for gas leak detection setups at home or in industrial environments. Plus, it features solid resistance to common interferents like ethanol and smoke, helping you get more accurate readings where it counts.\nWhether you’re building a safety system or experimenting with air quality monitoring, the MQ-2 is a tried-and-true option that won't break the bank.Please note: This is a hobbyist learning tool and not intended for use as a finished or safety product. It's all about the learning experience!\n\nView soldering guide here","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":377,"title":"Default Title","sku":"LB-LS4968","price":8.9,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":113,"option1":"Default Title"}]}
