|
||
|
|
|
||
|
|
## Tested on
|
||
|
|
|
||
|
|
1. ESP8266 RTOS_SDK v3.4
|
||
|
|
2. ESP32 ESP-IDF v5.2
|
||
|
|
|
||
|
|
## [Function description](http://zh-dht.zh.com.ru)
|
||
|
|

## Using
|
||
|
|
|
||
|
|
In an existing project, run the following command to install the component:
|
||
|
|
|
||
|
|
```text
|
||
|
|
cd ../your_project/components
|
||
|
|
git clone http://git.zh.com.ru/alexey.zholtikov/zh_dht.git
|
||
|
|
```
|
||
|
|
|
||
|
|
In the application, add the component:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#include "zh_dht.h"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Reading the sensor:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#include "zh_dht.h"
|
||
|
|
|
||
|
|
void app_main()
|
||
|
|
{
|
||
|
|
zh_dht_handle_t dht_handle = zh_dht_init(ZH_DHT22, GPIO_NUM_5);
|
||
|
|
float humidity;
|
||
|
|
float temperature;
|
||
|
|
for (;;)
|
||
|
|
{
|
||
|
|
zh_dht_read(&dht_handle, &humidity, &temperature);
|
||
|
|
printf("Humidity %0.2f\n", humidity);
|
||
|
|
printf("Temperature %0.2f\n", temperature);
|
||
|
|
vTaskDelay(5000 / portTICK_PERIOD_MS);
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
