How can a PHP script automatically exclude incorrect sensor values before calculating the average?

To automatically exclude incorrect sensor values before calculating the average in a PHP script, you can set a threshold for acceptable values and filter out any values that fall outside of this range. This can be done by iterating through the sensor values, checking each value against the threshold, and only including values that are within the acceptable range in the calculation of the average. 

// Sensor values array
$sensorValues = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110];

// Set threshold for acceptable values
$thresholdMin = 20;
$thresholdMax = 100;

// Filter out incorrect values
$filteredValues = array_filter($sensorValues, function($value) use ($thresholdMin, $thresholdMax) {
    return $value >= $thresholdMin && $value <= $thresholdMax;
});

// Calculate average of filtered values
$average = array_sum($filteredValues) / count($filteredValues);

echo "Average of filtered sensor values: " . $average;
