Read temperature sensors of the odroid

First find the files the kernel drops in the sys file system

find /sys -iname *temp*
/sys/devices/platform/samsung-fake-battery/power_supply/battery/batt_temp
/sys/devices/platform/samsung-fake-battery/power_supply/battery/batt_temp_adc
/sys/devices/platform/samsung-fake-battery/power_supply/battery/batt_temp_adc_cal
/sys/devices/platform/tmu/temperature
/sys/devices/platform/tmu/throttle_temp
/sys/devices/platform/tmu/warning_temp

Then cat the one you want to know

cat /sys/devices/platform/tmu/temperature
