TrustKernel PlugMate : Secure Miniature USB-C Computer running PlugOS · File : plugmate-thermal-throttle-check-8.ino · Language : bash · Use case : Surveiller la température CPU via le sysfs pour gérer les seuils thermiques dus au format compact.

Thermal monitoring script via sysfs for MediaTek SoC.

PlugMate is passive and very compact, thermal management is critical. This script reads standard Linux thermal zones (MTK8195/8168 drivers). Execution requires root privileges or ADB shell with sysfs node access. Run in background to prevent overheating.
