Description: 1. The Fermion MEMS (Micro-Electro-Mechanical Systems) Formaldehyde HCHO Gas Detection Sensor is a compact, high-sensitivity gas sensor designed for detecting formaldehyde gas in various environments. 2. Principal Technology: Utilizes a surface acoustic wave (SAW) MEMS technology to convert physical gas concentration changes into electrical signals for precise measurement and detection. 3. Detection Limit: Capable of sensing formaldehyde concentrations as low as 1 ppm, making it suitable for indoor air quality monitoring applications and industrial processes. 4. Form factor and Connectivity: Available in a small form factor (LGA: Land Grid Array) measuring 3mm x 3mm x 0.9mm, and offers I²C interface for easy integration into IoT systems and various microcontrollers. 5. Operating Temperature: Operates within the temperature range of -25°C to +85°C, ensuring reliable performance under diverse conditions. 6. Ease of Use and Integration: Simple, plug-and-play design allows for quick
