The SHTxx is a single chip relative humidity and temperature multi sensor module comprising a calibrated digital output. Application of industrial CMOS processes with patented micro-machining (CMOSens® technology) ensures highest reliability and excellent long term stability. The device includes a capacitive polymer sensing element for relative humidity and a band gap temperature sensor. Both are seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit on the same chip. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC) at a very competitive price. Each SHTxx is individually calibrated in a precision humidity chamber with a chilled mirror hygrometer as reference. The calibration coefficients are programmed into the OTP memory. These coefficients are used internally during measurements to calibrate the signals from the sensors .The 2-wire serial interface and internal voltage regulation allows easy and fast system integration. Its tiny size and low power consumption makes it the ultimate choice for even the most demanding applications. The device is supplied in either a surface-mountable LCC(Leadless Chip Carrier) or as a pluggable 4-pin single-in-line type package. Customer specific packaging options may be available on request.

Shtxx型器件是一種帶有標(biāo)準(zhǔn)數(shù)字輸出的相對濕度與溫度多模塊傳感器。它使用了CMOS生產(chǎn)技術(shù)從而保證了它的可靠性與穩(wěn)定性。該器件包括一個用于相對濕度檢測的電容傳感聚合物和一個帶隙溫度傳感器元件。它們都連接到一個14位的ADC和一個串行接口集成電路上。這樣就能夠使它產(chǎn)生高質(zhì)量的電信號并進行快速響應(yīng)和減弱外部的干擾。每個shtxx器件都以冷鏡面法作為標(biāo)準(zhǔn)在精密濕度室中進行單獨的標(biāo)準(zhǔn)化。此標(biāo)準(zhǔn)系數(shù)可在OPT存儲器中編程。
這個系數(shù)用于測量計算從傳感器內(nèi)部傳送來的標(biāo)準(zhǔn)電信號。兩線串行接口和內(nèi)部電壓調(diào)整它的小體積和低功耗使它成為那些最復(fù)雜應(yīng)用設(shè)計上的最終選擇。
此設(shè)備可供應(yīng)一個表面LCC或作為一個可插的4針單邊引出線的包裝。
