This is a HCHO(CH2O) sensor module. It can be used to measure HCHO in air. Through it, you can know the air quality. This sensor module is widely used in many air testing applications, such as indoor air quality, real time quality monitoring stations. Our HCHO sensor module can detect and measure HCHO accurately. Many advantages are available, such as strong anti-jamming capability, high stability, ATC, high sensitivity(up to 0.01ppm) and long life(2 years in air). Integrated with Gravity Interface which is easy to used, wide input voltage, and optional output signal, Our module can be almost compatible with all MCU. According our sample codes , an HCHO detector can be made very quickly.
“HCOH (Formaldehyde) is colorless, poisonous, high water-soluble, high alcohol-soluble and high ether-soluble gas with an obnoxious odor. It is widely used in decoration, such as adhesives, carpeting, decorative paneling and so on. HCOH is a prominent factor in sick-building syndrome …
