The SHT2x humidity sensor series contains a capacitive-type humidity sensor, a band-gap temperature sensor, and specialized analog and digital integrated circuits – all on a single CMOSens® chip. This yields superior sensor performance in terms of accuracy and stability as well as minimal power consumption. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out on command. Furthermore, the resolution of the SHT2x humidity sensor can be changed on command (8/12 bit up to 12/14 bit for RH/T) and a checksum helps to improve communication reliability. With this set of features and its proven reliability and long-term stability, the SHT2x humidity sensor series offers an outstanding price-performance ratio. To test a humidity sensor from the SHT2x series, two evaluation kits, EK-H4 and EK-H5, are available.\n\nLibDriver SHT2X is a full-featured driver for SHT2X, launched by LibDriver.It provides temperature reading, humidity reading, serial number reading and additional features. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver SHT2X source files.\n\n/interface includes LibDriver SHT2X IIC platform independent template.\n\n/test includes LibDriver SHT2X driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver SHT2X sample code.\n\n/doc includes LibDriver SHT2X offline document.\n\n/datasheet includes SHT2X datasheet.\n\n/project includes the common Linux and MCU development board sample code.
