I've created a sensor to take readings daily .
Humidity =
20×1 string array
"34.099045"
"42.425098"
"33.480418"
"35.790796"
"30.370059"
"44.029928"
"49.041827"
"44.980187"

Again you have 20 rows in humidity data but 10 rows in humidity time. How do they match? If they match by rows, you can use HumidityTime(double(humidity) > 40 & double(humidity) < 50, :) to get the times that humidity meet your defined criterion.

Humidity = str2double(Humidity(~ismissing(Humiditiy)));
lowlimit = 40;
highlimit = 50;
outsidelimit = Humidity > highlimit || Humidity < lowlimit;
alerts = [HumidityTime(outsidelimit,:) Humidity(outsidelimit)];

At the time you get that output, what is the string array that you are starting with ?
