How to Fetch and Display Data from DHT22 Sensor on AVR32UC with Zephyr OS?

#include <zephyr.h>
#include <device.h>
#include <drivers/sensor.h>
#include <sys/printk.h>

const struct device *sensor_dev;

void main(void)
{
    struct sensor_value temp, humidity;

    sensor_dev = device_get_binding(DT_LABEL(DT_INST(0, ams_dht22)));
    if (!sensor_dev) {
        printk("Failed to bind DHT22 sensor\n");
        return;
    }

    if (sensor_sample_fetch(sensor_dev) < 0) {
        printk("Failed to fetch data\n");
        return;
    }

    sensor_channel_get(sensor_dev, SENSOR_CHAN_AMBIENT_TEMP, &temp);
    sensor_channel_get(sensor_dev, SENSOR_CHAN_HUMIDITY, &humidity);

    printk("Temperature: %d.%d C\n", temp.val1, temp.val2);
    printk("Humidity: %d.%d %%\n", humidity.val1, humidity.val2);
}
