High Sensitivity and Versatility: The MICS-5524 Air Quality Gas Sensor Module is a remarkable addition to any for Arduino DIY project, offering remarkable high sensitivity to a range of gases including carbon monoxide (0.1 to 1000 ppm), ammonia (0.1 to 500 ppm), ethanol (10 to 500 ppm), hydrogen (0.1 to 1000 ppm), methane (1000++ ppm), and propane (1000++ ppm). This sensor's versatility makes it an excellent tool for indoor air quality monitoring, fire detection, and even as a breath checker component. Ease of Use and Energy Efficiency: The MICS-5524 Gas Sensor is incredibly user-friendly, requiring only 5 VDC power supply and simple analog voltage reading off the output pin. The heater draws about 25-35mA, which is an energy-efficient design for continuous monitoring. The EN pin allows for easy power management, allowing you to turn off the sensor by pulling it high to 5V when not in use, conserving energy. Customization and Compatibility: The MICS-5524 Gas Sensor is customizable to suit your specific needs, making it a valuable asset for both hobbyists and professionals alike. Its compatibility with the for Arduino platform makes it a natural fit for a wide range of DIY projects, from home automation to industrial monitoring. The module comes with a small header for easy soldering, ensuring a quick and secure connection. This gas sensor is not only a reliable tool for detecting harmful gases but also a versatile component for innovative projects. The MiCS-5524 is a robust MEMS sensor for indoor carbon. monoxide and natural gas leakage detection, it's suitable also for indoor air quality nonitoring; breath checker and early fire detection. Please note: This sensor is sensitive to CO(~1 to 1000 ppm), Ammonia (~1 to 500 ppm), Ethanol (~10 to 500 ppm), H2(~1-1000 ppm), Methane / Propane /Iso-Butane (~1,000++ ppm).
