Fermion MEMS Gas Detection Sensor Carbon Monoxide (CO) (Breakout, 5-5000ppm)

🧪 Fermion MEMS CO Gas Sensor
🧩 Overview
Compact carbon monoxide (CO) gas detection sensor
Based on MEMS (Microelectromechanical Systems) technology
Designed for low-power air quality and safety monitoring
Compatible with Arduino, ESP32, Raspberry Pi
⚙️ Working Principle
CO gas interacts with MEMS sensing material
Causes change in sensor resistance (chemiresistive effect)
Circuit converts change → analog voltage output
Microcontroller interprets signal → CO concentration trend
👉 Designed for qualitative detection (relative measurement)
