The ZE07-CH2O module employs a mature electrochemical sensing principle specifically tuned for formaldehyde (CH2O) detection, ensuring high selectivity against common interfering gases like alcohol and CO. Its sophisticated internal signal conditioning circuitry provides excellent linear output and stability across its 0 to 5 ppm measurement range.
Designed for reliable operation in environments from 0°C to 50°C and 15% to 90% relative humidity (non-condensing), the module is suited for continuous monitoring applications. The combination of low power consumption and multiple output options makes it a versatile solution for integrating precise formaldehyde measurement into smart home devices, HVAC controls, and portable air quality analyzers.
