Fermion: MEMS HCHO Sensor

SKU: SEN0563

Fermion: MEMS HCHO sensor uses MEMS technology for compact dimensions (13x13x2.5mm), low power consumption (<20mA), minimal heat generation, short preheating time, and swift response recovery. It qualitatively measures formaldehyde gas, suitable for air purifiers, HVAC systems, smart wearables, and portable detectors. The MEMS series includes 11 gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2) that can be combined. Note: This sensor is qualitative only. For quantitative measurements, consider the [Factory-calibrated Gas Sensor](https://www.dfrobot.com.cn/goods-3423.html).
