The HTU31 is one of the smallest and most accurate humidity sensors on the market. TE Connectivity precision engineering and 20+ years of experience in humidity and temperature combination sensors, enabled this new product with fast response time, precision measurement, low hysteresis, robustness to reflow assembly process and sustained performance even when exposed to extreme temperature [-40° to 125°C] and humidity [0%RH to 100%RH] environments.
LibDriver HTU31D is the full function driver of HTU31D launched by LibDriver.It provides the function of reading temperature and relative humidity. LibDriver is MISRA compliant.
/src includes LibDriver HTU31D source files.
/interface includes LibDriver HTU31D IIC platform independent template.
/test includes LibDriver HTU31D driver test code and this code can test the chip necessary function simply.
/example includes LibDriver HTU31D sample code.
/doc includes LibDriver HTU31D offline document.
/datasheet includes HTU31D datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
/misra includes the LibDriver MISRA code scanning results.
Reference /interface IIC platform independent template and finish your platform IIC driver.
Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.
You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.
