How Can I Consistently Handle Sensor Data Read Failures on AVR32UC with Zephyr OS?

hey guys does anyone have idea on how can I consistently handle sensor data read failures on the AVR32UC microcontroller and address the persistent issue of sensor data read failures using the Zephyr OS? I implemented an error handling code to manage and report sensor data read failures consistently. Despite this implementation, the persistent issue of sensor data read failure remains unresolved. How can this be effectively addressed?
my code setup:
#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;
    }

    while (1) {
        if (sensor_sample_fetch(sensor_dev) < 0) {
            printk("Failed to fetch data\n");
            k_sleep(K_SECONDS(5));
            continue;
        }
        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);

        k_sleep(K_SECONDS(10));
    }
}
#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;
    }

    while (1) {
        if (sensor_sample_fetch(sensor_dev) < 0) {
            printk("Failed to fetch data\n");
            k_sleep(K_SECONDS(5));
            continue;
        }
        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);

        k_sleep(K_SECONDS(10));
    }
}

when this is successful, it is expected that the AVR32UC microcontroller should handle sensor data read failures consistently, retrying fetch attempts, and accurately reporting temperature and humidity data from the DHT22 sensor.
Solution
To handle sensor data read failures more effectively on the AVR32UC microcontroller using Zephyr OS, you can refine your approach by implementing a more robust error-handling mechanism Like:

Retry Mechanism
Error Reporting
Initialization Check
Power Management
Check for Sensor Compatibility
