Temperature control is a critical requirement inmany industrial heating applications where accurate sensing and reliable power regulation are necessary for system stability and safety. This paper presents the design and implementation of a microcontroller-based temperature monitoring and control system utilizing a thermocouple sensor and dual-heater regulation. The proposed system employs a thermocouple temperature sensor interfaced through a thermocouple-to-digital converter toobtain accurate temperature measurements. A microcontroller processes the temperature data and compares it with a user-defined setpoint to perform closed-loop temperature control.The system integrates a user interface consisting of key switches for parameter adjustment and a four-digit seven-segment display for real-time visualization of temperature values and system status. Heater control is achieved through optoisolated triac driver circuits that enable safe switching of ACpower to the heating elements. Additional peripheral modules including LED indicators, a buzzer alarm circuit, and a cooling fan control mechanism are incorporated to enhance operational feedback, safety, and thermal stability. The designed architecture ensures electrical isolation between the low-voltage control circuitry and high-voltage heater loads,improving system reliability and user safety. Experimental evaluation demonstrates that the system provides stable temperature regulation, responsive user interaction, and reliable heaterswitching performance. The proposed design offers a cost-effective and scalable solution suitable for industrial heating systems, laboratory equipment, and temperature-sensitive process control applications.

Power quality issues and voltage fluctuations continue to pose significant challenges to the reliable operation of electrical equipment. This paper develops a microcontroller based programmable voltage monitoring and protection system using a Proteus virtual environment. The design in corporates a virtual Arduino controller, an AC source with adjustable load conditions, and an integrated signal-conditioning module to feature display and relay-based control components. A real-time graphical interface and an LCD module are used to continuously display input and regulated output voltages during operation. The system intelligently detects deviations beyond an acceptable voltage range and initiates protective shutdown to safeguard connected loads. The complete functionality is validated through comprehensive virtual prototyping, to demonstrate a practicaland cost-efficient approach for pre-hardware evaluation of programmable reference systems in voltage regulation and protection applications.
