| Abstract | This study aimed to develop a remote control and monitoring system for smart greenhouse by using the advantages of the information and communication technology, including smartphone and internet. Specific objectives of the study were: (a) to design a control and data acquisition system which integrates control of temperature, humidity, light luminance, and soil moisture content; (b) to design internet - based remote control system with surveillance camera which empowers the advantages of internet in order to make the system be securely accessed from anywhere; and (c) to conduct test of performance to obtain reliability specifications of the system by installing the control system on a model greenhouse. The system consists of sensors, camera and actuators connected to personal computer via interfaces using microcontroller. Supporting software was composed and installed on the computer to handle the overall control operation including remote access via internet connection. Performance of the system was investigated by installing it in a model greenhouse equipped with actuators for temperature control (fans), humidity control (water sprayer), light control (mechanical shading), and water/nutrient requirement control (water pump). Lettuce plants were cultivated using hydroponic arrangement inside the greenhouse during the experiment. The plant growth was monitored and recorded while controlling microclimate (temperature, humidity, light, and soil moisture). Remote Desktop ® was activated on the computer so that the supported remote devices (Laptops, smartphones, or tablets) could access the control system remotely via internet or intranet. Results of the test indicate that automatic mode for temperature and humidity control allowed these parameters fluctuated within desired range; manual control of mechanical shading and plastic cover was capable to reduce light intensity varying between 8 – 12% depend on the level of opening blades; timer mode for watering resulted fluctuation of moisture content 10 cycles in 3 hours. Surveillance unit provided pictures of plant growth that offers additional information to be considered for making a control decision. |
