I don't want array to do word splitting - bash

Question

Below is my code. But bash is doing word splitting therefore I have failure. How to make my script so that there is no word splitting.
namaSensor=$(sensors | egrep "°C" | awk '{print $0}' | awk -F ':' '{print $1}')
for sensor in $namaSensor
do
if [ $(sensors | grep -c "$sensor") -ne 0 ]
then
currentTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $2}' | cut -c 1-4 | awk -F '.' '{print $1}')
maxTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $3}' | cut -c 1-4 | awk -F '.' '{print $1}')
if [ $currentTemperature -lt $maxTemperature ]
then
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is within the maximum allowed temperature\n"
echo "$sensor"
else
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is more than the maximum allowed temperature\n"
#exit 255
fi
fi
done.
This is the output of sensors for my unit.

Please help

As I understand you have your array splitted as following:
Physical
id
0
and so on. To change this behaviour you need to change your Internal Field Separator (IFS) to a newline. So your code should look like this:
IFS=$'\n'
nameSensor=$(sensors | egrep "°C" | awk '{print $0}' | awk -F ':' '{print $1}')
for sensor in $nameSensor
do
if [ $(sensors | grep -c "$sensor") -ne 0 ]; then
currentTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $2}' | cut -c 1-4 | awk -F '.' '{print $1}')
maxTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $3}' | cut -c 1-4 | awk -F '.' '{print $1}')
if [ $currentTemperature -lt $maxTemperature ]; then
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is within the maximum allowed temperature\n"
echo "$sensor"
else
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is more than the maximum allowed temperature\n"
#exit 255
fi
fi
done
