2. OUTLINE

3. ABSTRACT A digital thermostat that employs a Finite State Machine (FSM) provides accurate temperature regulation while maximizing energy efficiency. It shifts between states such as Idle, Heating, and Cooling according to real-time temperature readings, which helps avoid constant toggling and boosts system stability. This method enhances efficiency, reliability, and makes it ideal for smart home environments .

4. MOTIVATION A digital thermostat that utilizes a finite state machine (FSM) offers efficient temperature regulation, lower energy usage, and greater system stability. In contrast to conventional methods, FSM minimizes the need for constant switching, optimizes energy consumption, and boosts reliability. This method is particularly well-suited for smart homes and automated HVAC systems, delivering a cost-effective and scalable solution.

7. CONCLUSION This FSM-based digital thermostat ensures efficient temperature control, reduces power consumption, and improves user comfort. The FSM approach simplifies the system logic, making it reliable and scalable for future enhancements, such as IoT integration for remote monitoring. Use FSM with Verilog (FPGA/ASIC) for high-speed, low-power, and real-time critical applications (e.g., industrial automation).
