ZE08CH2O Formaldehyde Sensor Module Realtime measurement of formaldehyde concentrations to ensure data accuracy and reliability. UART serial output for easy integration with a wide range of microcontrollers and development boards. Suitable for homeowners concerned about indoor air quality, environmental agencies, and academic researchers studying air pollutants. Ideal for indoor air monitoring in homes, offices, and schools, and for detecting formaldehyde in newly renovated spaces and industrial settings. Key attributes: function is formaldehyde detection; compatibility through UART interface; performance enables continuous realtime data. Use scenarios: 1) Residential renovation or postrenovation evaluation: monitor formaldehyde release to verify IAQ before occupancy. 2) Office and school IAQ monitoring: maintain acceptable formaldehyde levels and support safety compliance. 3) Industrial environments: detect formaldehyde presence in production or storage areas to ensure safety.
