Description

The Fermion MEMS Odor Smell Gas Detection Sensor is a high-sensitivity, low-power gas detection module designed using advanced microelectromechanical system (MEMS) technology. Measuring only 13×13×2.5mm, this compact sensor consumes less than 20mA of current and provides rapid response and recovery times. It can qualitatively detect odor-related gases such as H₂S, EtOH, and Acetone, making it ideal for applications like breath detection, food spoilage monitoring, body odor analysis, and health-related sensing projects. The sensor features an analog voltage output, operates between 3.3V and 5V, and performs reliably across a wide temperature range (-10°C to +50°C). Designed for educational, research, and IoT use, the Fermion MEMS sensor is a versatile tool for developing odor-based detection systems or electronic noses using platforms like Edge Impulse.
