IDT ZMOD4410室内气体传感器解决方案
IDT公司的ZMOD4410是用来检测总挥发性有机物(TVOC)和监测室内空气质量(IAQ)的气体传感器模块,包括气体检测元件和CMOS信号调理IC(IDT的ZSSC3250).模块的检测元件包括基于硅(Si)MEMS结构的加热元件和金属氧化物(MOX)化学电阻器,而信号调理器控制传感器温度和测量MOx导电率(气体浓度的函数).I2C接口高达400kHz,可调ADC分辨率,最高16位,内置用户数据的非易失存储器(NVM),工作温度-40℃ 到65℃,工作电压1.7V到3.6V,主要用在室内空气检测,用于健康和舒适的家庭,办公室和个人环境的监视器,检测有害材料和不健康条件如建筑材料烟雾.本文介绍了ZMOD4410主要特性,框图,应用电路以及评估板ZMOD4410 EVK主要特性,通信板和传感器板电路,材料清单和PCB设计图.
Automation based on indoor ambient air quality (HVAC, airpurifiers, thermostats, etc.)The ZMOD4410 Gas Sensor Module is designed for detecting totalvolatile organic compounds (TVOC) and monitoring indoor airquality (IAQ). It is a 12-pin LGA assembly (3.0 x 3.0 x 0.7 mm) thatconsists of a gas sense element and a CMOS signal conditioning IC (IDT’s ZSSC3250). The module’s sense element consists ofheater element on a Si-based MEMS structure and a metal oxide(MOx) chemiresistor. The signal conditioner controls the sensortemperature and measures the MOx conductivity, which is afunction of the gas concentration.
