Formaldehyde Sensor CJSH22-CH2O – Compact, High-Precision VOC Detection
Ultra-compact design for seamless integration in tight spaces, ideal for smart home devices and portable air quality monitors. High-precision electrochemical sensor delivers reliable formaldehyde detection with minimal cross-sensitivity to other VOCs, ensuring accurate indoor air quality assessments. Low power consumption (typically <30mA) extends battery life, perfect for continuous monitoring in IoT applications and wireless environmental systems. Robust ceramic-based sensing element with gold electrodes ensures long-term stability and resistance to humidity fluctuations. Wide detection range (0–5ppm) covers residential, industrial, and laboratory scenarios, from new furniture off-gassing to chemical storage safety. Pre-calibrated for plug-and-play operation, reducing setup time for HVAC professionals and DIY smart home enthusiasts. Industrial-grade ABS housing with anti-interference shielding guarantees durability in high-EMF environments like factories or server rooms. RS485/analog output options for flexible connectivity to Arduino, Raspberry Pi, or industrial control systems.
