In view of the poor temperature and humidity control effect of heating, ventilation and air conditioning(HVAC)due to low detection accuracy and imperfect control process, an intelligent temperature and humidity control technology of HVAC based on photoelectric sensor is proposed. The photoelectric component of the photoelectric sensor is analyzed, the optical circuit of the photoelectric sensor is designed, the temperature is collected through the resonant frequency of the composite cantilever beam, and the current environmental humidity is obtained by measuring the voltage changes on both sides of the resistance of the sensor. The detected data is input into the constructed temperature and humidity intelligent control system, and the parameters of PID controller are optimized by shuttled frog leaping algorithm(SFLA)to control the temperature and humidity of HVAC to keep within the set range, so as to realize the intelligent control of temperature and humidity of HVAC. The experimental results show that the temperature error of the designed temperature and humidity intelligent control technology is less than 0.02 ℃,in the case of external interference, the control temperature is 26 ℃,the humidity value is 80%RH,therefore, The temperature and humidity can be effectively controlled in the set range through this technology, which has the feasibility and effectiveness.
