The DFRobot Threshold Formaldehyde HCHO Detection Sensor is a professional-grade module designed to detect hazardous levels of formaldehyde (HCHO) in air. Operating on a fixed threshold of 0.075mg/m³ (0.06ppm), the sensor triggers instant high/low-level outputs when this safety limit is exceeded. A built-in LED status indicator provides immediate visual alerts, making it ideal for real-time air quality monitoring in homes, schools, labs, and industrial environments. With a fast response time of under 15 seconds, it quickly identifies potentially dangerous changes in air quality. The Threshold Formaldehyde HCHO Detection Sensor supports a wide input voltage range (5–24V DC), offering flexible integration into various systems. Built with a compact and flame-retardant PVC housing, it’s durable enough for demanding applications, while remaining small enough for discreet installations. It’s a simple, cost-effective solution for ensuring safety from formaldehyde exposure without requiring calibration or configuration—ready to use out of the box.
