# ESP32 ESP-IDF and ESP8266 RTOS SDK component for 1-Wire DS18B20 sensor

## Tested on

1. ESP8266 RTOS_SDK v3.4

2. ESP32 ESP-IDF v5.2

## Dependencies

1. [zh_onewire](https://github.com/aZholtikov/zh_onewire.git)

## Using

In an existing project, run the following command to install the components:

```text

cd ../your_project/components

git clone https://github.com/aZholtikov/zh_onewire.git

git clone https://github.com/aZholtikov/zh_ds18b20.git

```

In the application, add the component:

```c

#include "zh_ds18b20.h"

```

## Examples

One or more 1-Wire DS18B20 sensors on bus:

```c

#include "zh_ds18b20.h"

void app_main(void)

{

    esp_log_level_set("zh_onewire", ESP_LOG_NONE);

    esp_log_level_set("zh_ds18b20", ESP_LOG_NONE);

    uint8_t *rom = NULL;

    float temperature = 0.0;

    zh_onewire_init(GPIO_NUM_5);

    if (zh_onewire_reset() != ESP_OK)

    {

        printf("There are no 1-Wire devices available on the bus.\n");

    }

    else

    {

        zh_onewire_search_rom_init();

        for (;;)

        {

            rom = zh_onewire_search_rom_next();

            if (rom == NULL)

            {

                break;

            }

            printf("Found device ROM: ");

            for (uint8_t i = 0; i < 8; ++i)

            {

                printf("%X ", *(rom++));

            }

            printf("\n");

            rom -= 8;

            zh_ds18b20_read(rom, &temperature);

            printf("Temperature: %0.2f\n", temperature);

        }

    }

}
