## LibDriver SHT85

[![MISRA](https://img.shields.io/badge/misra-compliant-brightgreen.svg)](/misra/README.md) [![API](https://img.shields.io/badge/api-reference-blue.svg)](https://www.libdriver.com/docs/sht85/index.html) [![License](https://img.shields.io/badge/license-MIT-brightgreen.svg)](/LICENSE)

SHT85 is Sensirion’s best-in-class humidity sensor with pin-type connector for easy integration and replacement. It builds on a highly accurate and long-term stable SHT3x sensor that is at the heart of Sensirion’s strongly established humidity and temperature platform. The unique package design allows for the best possible thermal coupling to the environment and decoupling from potential heat sources on the main board. The SHT85 features a PTFE membrane dedicated to protecting the sensor opening from liquids and dust according to IP67, without affecting the response time of the RH signal. It thus allows for sensor use under harsh environmental conditions, (such as spray water and high exposure to dust). Sensirion holds an exclusive license for several patents for employing an on-package filter membrane on a humidity sensor. Final accuracy testing on product level ensures best performance, making the SHT85 the ultimate choice for even the most demanding applications.

LibDriver SHT85 is a full-featured driver for SHT85, launched by LibDriver.It provides continuous reading, single reading and additional features. LibDriver is MISRA compliant.

### Instruction

/src includes LibDriver SHT85 source files.

/interface includes LibDriver SHT85 IIC platform independent template.

/test includes LibDriver SHT85 driver test code and this code can test the chip necessary function simply.

/example includes LibDriver SHT85 sample code.

/doc includes LibDriver SHT85 offline document.

/datasheet includes SHT85 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.

### Install

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.

### Usage

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.

#### example basic

```C
#include "driver_sht85_basic.h"

uint8_t res;
uint32_t i;
float temperature;
float humidity;
uint8_t sn[4];

/* basic init */
res = sht85_basic_init();
if (res != 0)
{
    return 1;
}

...
    
/* loop */
for (i = 0; i < 3; i++)
{
    /* delay 1000ms */
    sht85_interface_delay_ms(1000);

    /* read data */
    res = sht85_basic_read((float *)&temperature, (float *)&humidity);
    if (res != 0)
    {
        (void)sht85_basic_deinit();

        return 1;
    }

    /* output */
    sht85_interface_debug_print("sht85: %d/%d.\n", (uint32_t)(i + 1), (uint32_t)3);
    sht85_interface_debug_print("sht85: temperature is %0.2fC.\n", temperature);
    sht85_interface_debug_print("sht85: humidity is %0.2f%%.\n", humidity);
    
    ...
}

...

/* get serial number */
res = sht85_basic_get_serial_number(sn);
if (res != 0)
{
    sht85_basic_deinit();

    return 1;
}
sht85_interface_debug_print("sht85: serial number is 0x%02X 0x%02X 0x%02X 0x%02X.\n", sn[0], sn[1], sn[2], sn[3]);

...
    
/* basic deinit */
(void)sht85_basic_deinit();

return 0;
```

#### example shot

```C
#include "driver_sht85_shot.h"

uint8_t res;
uint32_t i;
float temperature;
float humidity;

/* shot init */
res = sht85_shot_init();
if (res != 0)
{
    return 1;
}

...
    
/* loop */
for (i = 0; i < 3; i++)
{
    /* delay 1000ms */
    sht85_interface_delay_ms(1000);

    /* read data */
    res = sht85_shot_read((float *)&temperature, (float *)&humidity);
    if (res != 0)
    {
        (void)sht85_shot_deinit();

        return 1;
    }

    /* output */
    sht85_interface_debug_print("sht85: %d/%d.\n", (uint32_t)(i + 1), (uint32_t)3);
    sht85_interface_debug_print("sht85: temperature is %0.2fC.\n", temperature);
    sht85_interface_debug_print("sht85: humidity is %0.2f%%.\n", humidity);
    
    ...
}

...
    
/* shot deinit */
(void)sht85_shot_deinit();

return 0;
```
