The ideal energy-saving building should meet the environmental quality of living space in different seasons with the least energy consumption. The indoor temperature of the building is an important consideration. However, most temperature control systems have certain problems. In order to improve the stability and accuracy of the temperature control system, a system based on FPGA+Verilog HDL for intelligent adjustment of indoor temperature is designed. The purpose of the system design is to achieve the dual effect of comfortable and energy-saving living environment. The system uses an integrated temperature sensor DS18B20 as a temperature sensing element. FPGA as the master control center to process data. The system is programmed with the hardware description language Verilog HDL. The temperature control system uses a digital PID control algorithm. The simulation results verify the correctness of the design.
