This sensor qualitatively measures the concentration of formaldehyde gas, making it suitable for applications in air purifiers, HVAC systems, smart wearables, portable detectors, and more.The MEMS series currently encompasses 11 different types of gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2), which can be combined as per specific requirements.Please note: This sensor is capable of qualitative measurements only. For quantitative measurements, kindly consider purchasing the Gravity: Factory Calibrated Electrochemical Gas Sensor Series.Figure: Wiring Diagram of Fermion: MEMS HCHO Sensor and Arduino UNOPrecautions for useKindly remove the protective film before usage.To prevent exposure to volatile silicon compounds vapors (such as silicone adhesive, hair gel, silicone rubber, or other locations where volatile silicon compounds are present).Avoid exposure to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.).Prevent contamination from alkalis, alkali metal salts, and halogens.Refrain from prolonged exposure to extreme environments (such as high temperatures, high humidity, high pollution).Avoid contact with water, condensation, and freezing.Minimize excessive vibration, impact, and dropping.Please refrain from employing this module in systems that involve personal safety concerns.For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.\nFeatures\nCompact size, measuring only 13*13*2.5mm Low power consumption,operating current <20mAHigh sensitivity and rapid response recoveryAdvanced MEMS technology\nApplications\nAir purifiersHVAC systemsSmart wearablesPortable detectors \nSpecification\nGas detected: HCHODetection range: 0-3ppmOperating voltage: 3.3-5VOperating current: <20mAOutput signal: Analog voltageSensitivity: R0(in air)/Rs(in 0.4ppm HCHO) ≥ 1.8Operating temperature: -10-50°COperating humidity: 15-90%RH (non-condensing)Lifespan: ≥3 years (in air)Dimension: 13×13 x 2.5mm/ 0.0.51×0.51x0.1\"\nProjects\n\nProject: Building an Electronic Nose with MEMS Gas Detection Sensor Breakout Series and Edge Impulse PlatformIntroduction: In this project, I developed an electronic nose using DFRobot mems series gas sensors and the Edge Impulse platform, which is capable of identifying the scents of beverages and fruits.\nDocuments\nProduct wikiSchematics & DimensionCharacteristic Parameter\nShipping List\nFermion: MEMS Formaldehyde HCHO Gas Detection Sensor (breakout) × 12.54mm pitch header pin × 1","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1483,"title":"Default Title","sku":"DF-SEN0563","price":8.3,"on_sale":false,"in_stock":true,"available_quantity":235,"option1":"Default Title"}]}
