Project in engineering, this presentation explores the design and use of vegetable crops by how to grow Hydroponic style by using the incoming control PLC application to automation of compound fertilizer to create moisture and temperature, with the plant. With the application of touch screen technology (Touch Screen) control set to the PLC and the sensor 5 sensor type, pH-value measuring for checking the quality of pure water, the conductivity sensor for monitoring the fertilizer value.The fertilizer in the hopper that there is too much or too little, the water temperature sensor for monitoring the water too hot, because it may cause root rot, in air and measuring the relative humidity sensor for monitoring the working environment, appropriate crops by five sensors of this type o.The settings for the PLC in order to check the condition of the programs wrote. When completed the results to make adjustments. In the field of concentrations of fertilizer in the water will pour in fertilizer until the update is installed on your system, the acid – alkaline in water by the acid ionization is pre-equipped acid. – The values are alkali, adjust the temperature in the water with the method of opening the fan blowing into the water to reduce the temperature in the water is higher than the values set in the program, adjust relative air temperature and tastes around area with open spray mist by the time. in the updates.To adjust the environment suitable for cultivating this Hydroponic system can operate effectively and efficiently and help reduce the cost of employing workers. Conserve the environment by using circulating water Convenience to the user, in the case of the cultivation in the major attractions also are warning (Alarm). The various disorders in the event that the system could not update it to yourself. For example, is a solution of pH-adjusted out or malfunction of one of the water pump. These things cause tremendous damage if not corrected soon, hurry.
