Detailed Description

TempHum 27 Click example.

Description

This example demonstrates the use of the TempHum 27 Click board by reading ambient temperature and relative humidity values using periodic measurements. After initializing the device and starting the periodic mode at 1 Hz, the application waits for the ALERT pin to indicate data readiness and then logs the measurements to the USB UART terminal.

The demo application is composed of two sections :

Application Init

Initializes the logger and the Click driver, resets the device, reads and logs the sensor ID, and starts periodic measurements with a 1-second output rate.

Application Task

Waits for the ALERT pin to go low indicating new measurement data is available, then reads and logs the temperature and humidity values.

Note
If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
