SHT71

The calibration coefficients in the SHTxx sensors are programmed into the OTP memory and used internally during measurements to calibrate the signals from the sensors. Each SHTxx sensor is individually calibrated in a precision humidity chamber with a chilled mirror hygrometer as a reference

The SHTxx module described in the document includes a capacitive polymer sensing element for relative humidity and a bandgap temperature sensor. Both sensors are seamlessly coupled to a 14-bit analog-to-digital converter and a serial interface circuit on the same chip. This configuration results in superior signal quality, fast response time, and insensitivity to external disturbances at a competitive price. Each SHTxx sensor is individually calibrated in a precision humidity chamber with a chilled mirror hygrometer as a reference, and the calibration coefficients are programmed into the OTP memory for internal use during measurements. The sensors are designed for highest reliability and excellent long-term stability, making them suitable for demanding applications. The sensors have a 2-wire serial interface and internal voltage regulation for easy and fast system integration.

The applications mentioned for the SHT1x and SHT7x humidity and temperature sensors in the document include HVAC, automotive, consumer goods, weather stations, humidifiers, dehumidifiers, test & measurement, data logging, automation, white goods, and medical.
