Abstract

Loop-mediated isothermal amplification (LAMP) requires precise temperature control at 65°C for virus detection applications. Traditional portable systems face challenges in maintaining stable temperatures with limited power supplies. This paper presents the development of a portable temperature control system using an Arduino microcontroller integrated with a proportional-integral-derivative (PID) algorithm to address these limitations. The system employs a resistive heating element controlled via pulse width modulation (PWM) and powered through a USB 3.0 interface with a DC-DC boost converter. A Ktype thermocouple provides temperature feedback for closed-loop control. Experimental results demonstrate that the controller maintained the target temperature within ±2°C (65-67°C) for 35 minutes, meeting LAMP requirements. The system achieved the target temperature in 130 seconds with a maximum power consumption of 2.42W. This low-cost, portable solution enables field-deployable diagnostic applications with reliable temperature control performance.
