It provides a simple analogue voltage output that increases in proportion to the concentration of detected gas — just power it at 5V and read the analogue pin.\n\nThe sensor is suitable for indoor air quality monitoring, breath checking, and early fire detection applications. Note that while it detects multiple gas types, it cannot differentiate between them.\n\nKey Features\n\n\nMulti-Gas Detection – Sensitive to CO (~1–1000 ppm), Ammonia (~1–500 ppm), Ethanol (~10–500 ppm), H2 (~1–1000 ppm), and Methane/Propane/Iso-Butane (~1000+ ppm)\n\nAnalogue Output – Voltage increases proportionally with detected gas concentration\n\n5V Operation – Simple power and read interface\n\nEnable Pin – Pull high to power off the heater and conserve energy\n\nLow Heater Current – 25–35 mA when active\n\nMEMS Technology – Robust and compact sensor element\n\n\nIdeal For\n\nIndoor air quality monitoring projects\nGas leak detection experiments\nEducational sensor projects\nEnvironmental monitoring prototypes\n\n\nPackage Contents\n\n1× Adafruit MiCS-5524 Gas Sensor Breakout (assembled and tested)\n1× Header pin strip\n\n\n\nWarning: This sensor is for hobby, educational, and experimental use only — not for safety, medical, or finished product applications. The sensor cannot distinguish between different gas types. All gas sensors require calibration for precise readings.\n\n\n\nNote: Allow approximately one second after enabling the heater before taking readings. Some light soldering is required to attach the header.\n\n\nResources\n\nMiCS-5524 Tutorial & Example Code (Adafruit Learn)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11948,"title":"Default Title","sku":"AF-3199","price":29.92,"on_sale":false,"in_stock":true,"available_quantity":5,"option1":"Default Title"}]}
