Its performance has been greatly improved and has exceeded the reliability level of the previous generation sensor.The new generation of upgraded products have been improved to make their performance more stable in high temperature and high humidity environments; at the same time, the accuracy, response time, and measurement range of the product have been greatly improved.Each sensor is rigorously calibrated and tested before leaving the factory to ensure and satisfy customer’s large-scale applications. It can be used in HVAC, dehumidifier, testing and inspection equipment, consumer products, automobiles, automatic control, data loggers, weather stations, home appliances, humidity control, medical and other application fields which need to detect and control temperature and humidity.\n\nLibDriver DHT20 is a full-featured driver for DHT20, launched by LibDriver.It provides temperature reading, relative humidity 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 DHT20 source files.\n\n/interface includes LibDriver DHT20 IIC platform independent template.\n\n/test includes LibDriver DHT20 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver DHT20 sample code.\n\n/doc includes LibDriver DHT20 offline document.\n\n/datasheet includes DHT20 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
