[原创] TI HDC2010低功耗湿度和温度数字传感器解决方案

TI公司的HDC2010是低功耗高精度湿度和温度数字传感器,相对湿度范围0%-100%,湿度精度±2%,温度范围–40℃ - 125℃,温度精度±0.2℃,睡眠电流50nA,超紧凑WLCSP封装,工作电压1.8V,主要用在智能恒温器,电冰箱,冷冻运输车,洗衣机/干燥机,HVAC系统,气体检测,通信设备,环境检测标签,烟雾和热检测器,喷墨打印机,监视照相机,CPAP机器和可穿戴电子.本文介绍了HDC2010主要特性,功能框图和应用电路,以及评估模块HDC2010EVM特性,电路图,材料清单和PCB设计图.

The HDC2010 is an integrated humidity andtemperature sensor that provides high accuracymeasurements with very low power consumption, inan ultra-compact WLCSP (Wafer Level Chip ScalePackage). The sensing element of the HDC2010 isplaced on the bottom part of the device, which makesthe HDC2010 more robust against dirt, dust, and other environmental contaminants. The capacitivebasedsensor includes new integrated digital featuresand a heating element to dissipate condensation andmoisture. The HDC2010 digital features includeprogrammable interrupt thresholds to providealerts/system wakeups without requiring amicrocontroller to be continuously monitoring thesystem. This, combined with programmable samplingintervals, low inherent power consumption, andsupport for 1.8V supply voltage, make the HDC2010well suited for battery-operated systems.
