Library contains key functions used to read temperature and humidity data from the DHT22 2 click.

float DHT22_2_getTemperature();- Function for reading temperature from sensor

float DHT22_2_getHumidity()- Function for reading humidity from sensor

Examples Description

The example uses the library functions to read the temperature and humidity from the sensor and sends the data to the user, via the UART interface.
 

void applicationTask()
{
     temp = DHT22_2_getTemperature();
     humidity = DHT22_2_getHumidity();
     FloatToStr(temp,output);
     UART1_Write_Text("Temperature: ");
     UART1_Write_Text(output);
     UART1_Write_Text("°C");
     UART1_Write(13);
     UART1_Write(10);
     UART1_Write_Text("Humidity: ");
     FloatToStr(humidity,output);
     UART1_Write_Text(output);
     UART1_Write_Text("%");
     UART1_Write(13);
     UART1_Write(10);
     Delay_ms(1000);
}


Other mikroE Libraries used in the example:

  • UART
  • I2C

Additional notes and information

Depending on the development board you are using, you may need USB UART clickUSB UART 2 clickor RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
