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.
