Fermion: MEMS Gas Sensor - MiCS-5524 (Breakout)

This is an outstanding hydrogen and nitrogen oxide gas concentration sensor launched by DFRobot. Using advanced MEMS technology, it can detect the gas concentration of CO, CH4, C2H5OH, C3H8, C4H10, H2, H2S, and NH3. The included sample code integrates concentration conversion formulas for various gases, making it easy for you to test and use the sensor. It supports a 5V power supply, has an analog voltage output, and features power supply enable/disable pins for low - power consumption. Key features include support for multiple harmful gas detections, integrated gas concentration calculation formulas, low power consumption, I2C digital output, and compatibility with 3.3 - 5.5V master controllers. It's ideal for gas leak detection, gas safety equipment, and air environment detection. The sensor can detect gas concentration or leakage of specific gases, operates at 4.9 - 5.1V DC, has a power dissipation of 0.45W, and offers an analog output signal. Its measuring range varies for different gases, can work in a temperature range of - 30 to 85°C and humidity of 5 - 95%RH (no condensation), and has a lifespan of over 2 years in the air. The circuit board is 12mm x 16mm with mounting holes of inner diameter 2mm and outer diameter 4mm. Relevant documents like the product wiki, datasheet, schematics diagram, and dimension/layout are available.

Using this gas sensor is quite simple. First, connect it to a 3.3 - 5.5V master controller. You can use the 5V power supply provided. Make sure to use the power supply enable/disable pins to save power when not in full - time use. The sensor comes with sample code that has all the concentration conversion formulas. Just load the code onto your controller, and you're ready to start detecting gases. When it comes to gas leak detection, place the sensor in areas where gas leakage is likely. For air environment detection, put it in a well - ventilated area. Some things to keep in mind: don't expose the sensor to extreme temperatures outside the - 30 to 85°C range or humidity above 95%RH as it can damage the sensor. Also, don't let it come into contact with water or corrosive substances. For maintenance, keep the sensor clean. You can use a soft, dry cloth to gently wipe the surface if it gets dusty. Check the connections regularly to make sure they are secure. If you encounter any problems, refer to the product wiki or datasheet for more information.
