IDT ZMOD4410TVOC和室内空气质量传感器解决方案
IDT公司的ZMOD4410是总挥发性有机物(TVOC)和室内空气质量传感器,包括气体检测元件和CMOS信号调理IC.模块的检测元件基于Si的MEMS结构的加热元件和金属氧化物(MOx)化敏电阻器,而信号调理器控制传感器温度和测量MOx的导电率,它是气体浓度的函数.工作电压1.7V- 3.6V,主要用在室内空气监测,包括家庭,办公室和私人环境健康条件和舒适度,检测有害物质和有害健康条件等.本文介绍了ZMOD4410主要特性,框图,应用电路图,以及包括通信板和传感器板在内的评估板ZMOD4410 EVK主要特性,电路图,材料清单和PCB设计图.
The ZMOD4410 Gas Sensor Module is designed for detecting totalvolatile organic compounds (TVOC) and monitoring indoor airquality (IAQ) in different use cases. It is a 12-pin LGA assembly(3.0 x 3.0 x 0.7 mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module’s sense element consistsof heater element on a Si-based MEMS structure and a metaloxide (MOx) chemiresistor. The signal onditioner controls thesensor temperature and measures the MOx conductivity, which isa function of the gas concentration.
