Extracting Sensors Output into Sorted Array - bash

Question

this question is the continuation of Extracting Ubuntu Sensors Command Using Scripts
Since the question was poorly written, I'm rewording the question in form of new question.
Basically I want to extract GPUs temperatures information using sensors command and scripts like gawk and bash.
Example of sensors output will be like this:
amdgpu-pci-0c00
Adapter: PCI adapter
fan1: 1972 RPM
temp1: +50.0°C (crit = +0.0°C, hyst = +0.0°C)
amdgpu-pci-0600
Adapter: PCI adapter
fan1: 1960 RPM
temp1: +47.0°C (crit = +0.0°C, hyst = +0.0°C)
amdgpu-pci-0200
Adapter: PCI adapter
fan1: 1967 RPM
temp1: +52.0°C (crit = +0.0°C, hyst = +0.0°C)
pch_skylake-virtual-0
Adapter: Virtual device
temp1: +33.0°C
amdgpu-pci-0900
Adapter: PCI adapter
fan1: 1893 RPM
temp1: +51.0°C (crit = +0.0°C, hyst = +0.0°C)
amdgpu-pci-0300
Adapter: PCI adapter
fan1: 1992 RPM
temp1: +53.0°C (crit = +0.0°C, hyst = +0.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +24.0°C (high = +80.0°C, crit = +100.0°C)
Core 0: +23.0°C (high = +80.0°C, crit = +100.0°C)
Core 1: +21.0°C (high = +80.0°C, crit = +100.0°C)
The GPU temp information is labeled amdgpu-pci-"BUS_ID", so we don't care about other label scheme (skylake-virtual nor coretemp-isa). Things need to be done are:
Extracting the GPU temperatures info, for example amdgpu-pci-0c00
has 50 degree, and put in into an array.
The array index should be started with 0 and ascending in the order
of BUS ID.
If using the above data, the array assuming a is the name, would be:
a[0] = 52 ;amdgpu-pci-0200
a[1] = 53 ;amdgpu-pci-0300
a[2] = 47 ;amdgpu-pci-0600
a[3] = 51 ;amdgpu-pci-0900
a[4] = 50 ;amdgpu-pci-0c00
What I need for the output is an infinite loop that keep updating the array index with its value:
0 => 52
1 => 53
2 => 47
3 => 51
4 => 57
The new value should print over the old value so it won't trail. The update should have 1 second delay so the operator can easily evaluate the values.
The extracting and sorting could be done by GAwk, but I need it to be stored in an array in bash so that I can use it for other process.

Reusing parts from your script and Ed Mortons answer I think this might work for you:
#!/bin/bash
while true
do
while read -r i temp ; do
echo -en "GPU $i temp is $temp \r "
sleep 1
done < <(
sensors | gawk '
!NF {name=""}
/amdgpu/ {
name=$1
}
/^temp1:/ && name {
temps[name]=gensub(/^[^0-9]*([0-9]+).*/,"\\1",1,$2);
}
END {
PROCINFO["sorted_in"] = "#ind_str_asc"
ctr=0;
for (i in temps) {
print ctr++,temps[i]
}
} '
)
done
Edit: if you need to store the values to an array (as stated in the question) for other purposes you can do it like this:
temps=( $( sensors | gawk '...' ) )
In this case change the print command in awk to only print temps[i]. My approach can be easily extended to include other values from the sensors output (like the gpu labels or fan speed).
