Test temperature and alert

i have this script which result is cpu temp in celsius

first install:

apt-get install lm-sensors
YES |sensors-detect --auto

Code:

#!/bin/bash

# 1. get temperature

## a. split response
## Core 0:       +143.6�F  (high = +186.8�F, crit = +212.0�F)
IFS=')' read -ra core_temp_arr <<< $(sensors -f | grep '^Core\s[[:digit:]]\+:') #echo "${core_temp_arr[0]}"

## b. find cpu usage
total_cpu_temp=0
index=0
for i in "${core_temp_arr[@]}"; do :
    temp=$(echo $i | sed -n 's/�F.*//; s/.*[+-]//; p; q')
    let index++
    total_cpu_temp=$(echo "$total_cpu_temp + $temp" | bc)
done
avg_cpu_temp=$(echo "scale=2; $total_cpu_temp / $index" | bc)

## c. build entry
temp_status="CPU: $avg_cpu_temp F"
#echo $avg_cpu_temp
#echo $[(${avg_cpu_temp}*9/5)+32]
tc=$(echo "scale=2;(5/9)*($avg_cpu_temp-32)"|bc)
echo $tc=$avg_cpu_temp

this give a number like: 54

I want to have some condition, possible in new .sh and test if its ok or not.
For the start I want to tell temp is OK or not, just echo. Then i will figure out how to send to email.
I have something similar but for raspberry and mail function, but here on ubuntu i don't figure out just yet.

NAME

       sensors - print sensors information

SYNOPSIS

       sensors [ options ] [ chips ]
       sensors -s [ chips ]
       sensors --bus-list

DESCRIPTION

       sensors is used to show the current readings of all sensor chips.
       sensors -s is used to set all limits as specified in the configuration file.
       sensors --bus-list is used to generate bus statements suitable for the configuration file.

OPTIONS

       -c, --config-file config-file
	      Specify a configuration file. If no file is specified, the libsensors default configuration file is used. Use `-c /dev/null' to tem-
	      porarily disable this default configuration file.

       -h, --help
	      Print a help text and exit.

       -s, --set
	      Evaluate all `set' statements in the configuration file and exit. You must be `root' to do this. If this parameter is not specified,
	      no `set' statement is evaluated.

       -A, --no-adapter
	      Do not show the adapter for each chip.

       -u     Raw  output.  This mode is suitable for debugging and for post-processing of the output by scripts. It is also useful when writing a
	      configuration file because it shows the raw input names which must be referenced in the configuration file.

       -v, --version
	      Print the program version and exit.

       -f, --fahrenheit
	      Print the temperatures in degrees Fahrenheit instead of Celsius.

       --bus-list
	      Generate bus statements suitable for using in sensors.conf. Such bus statements are only needed if you have  several  chips  sharing
	      the  same  address  on  different buses of the same type. As bus numbers are usually not guaranteed to be stable over reboots, these
	      statements let you refer to each bus by its name rather than numbers.

FILES

       /etc/sensors3.conf
       /etc/sensors.conf
	      The system wide configuration file. See sensors.conf(5) for further details.
