It provides qualitative measurement of hydrogen concentration from 0.1 to 1000 ppm via an analogue voltage output, with low power consumption, fast response, and a short preheat time.\n\nAt just 13 × 13 × 2.5 mm, the sensor is one of the smallest hydrogen detectors available, making it suitable for integration into space-constrained designs. It operates on 3.3–5V and interfaces easily with Arduino and other microcontrollers.\n\nKey Features\n\n\nMEMS Technology – Ultra-compact sensor with low power and minimal heat generation\n\nHydrogen Detection – 0.1 to 1000 ppm range\n\nAnalogue Output – Simple voltage-based reading\n\nLow Power – Operating current <20 mA\n\nFast Response – Quick detection and rapid recovery\n\nLong Lifespan – 5+ years in normal air conditions\n\n3.3V and 5V Compatible – Works with Arduino, ESP32, and other platforms\n\n\nSpecifications\n\n\nGas Detected – Hydrogen (H2)\n\nDetection Range – 0.1–1000 ppm\n\nOperating Voltage – 3.3–5V\n\nOperating Current – <20 mA\n\nOutput Signal – Analogue voltage\n\nSensitivity – R0 (air) / Rs (200 ppm H2) ≥ 5\n\nOperating Temperature – -10°C to 50°C\n\nOperating Humidity – 15–90% RH (non-condensing)\n\nLifespan – ≥5 years (in air)\n\nDimensions – 13 × 13 × 2.5 mm\n\n\nIdeal For\n\nHydrogen leak detection and alarms\nFuel cell vehicle emission monitoring\nIndustrial safety and gas monitoring\nAir quality sensing applications\n\n\nPackage Contents\n\n1× Fermion MEMS H2 Sensor (Breakout)\n1× 2.54 mm Pitch Header Pin\n\n\nResources\n\nProduct Wiki\n\n\n\nWarning: Remove the protective film before use. Avoid exposure to volatile silicon compounds, high concentrations of corrosive gases (H2S, SOX, Cl2, HCl), alkalis, and halogens. Do not expose to water, condensation, or freezing. This module is for qualitative measurement only and should not be used in systems involving personal safety. After extended storage, preheat for at least 24 hours before use.\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1467,"title":"Default Title","sku":"DF-SEN0572","price":25.13,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":50,"option1":"Default Title"}]}
