Abstract

Paper presents automatic temperature control for plant house. Water evaporation technique is applied. The system has to water the plant and control temperature in range of 24-30 °C. Arduino Uno R3 was used as microcontroller. Temperature and humidity were detected by DHT sensors module. The four relays were used for controlling system. LCD screen showed condition of environment. Two pumps were used for watering plants and cooling pads. Cooling pads were use in cooling system applying water evaporation technique. A fan was installed on the top of house plant. For the construction of plant house, structure made of PVC tube. The house was covered by PVC canvas. Light can pass throughout. For watering system, ¼ inch tube was installed to water the plant. From experimental results show that the automatic system can be controlled temperature in the range of 24-28 °C. The relative humidity in house is approximately 75-90% while outside house is about 45-75%. Finally, the rate of growing in plant house by temperature control is higher about 30% than natural condition.

农业厂房温度自动控制

本文介绍了厂房温度的自动控制。采用水蒸发技术。该系统必须给植物浇水，并将温度控制在24-30°C的范围内。单片机采用Arduino Uno R3。温度和湿度由DHT传感器模块检测。四个继电器用于控制系统。液晶屏显示环境状况。两台水泵用于浇花和冷却垫。采用水蒸发技术在冷却系统中使用冷却垫。在室内植物的顶部安装了一台风扇。用于厂房建筑，结构采用PVC管。房子被聚氯乙烯帆布覆盖着。光可以穿透。对于浇水系统，安装了1 / 4英寸的管子来给植物浇水。实验结果表明，该自动系统可将温度控制在24-28℃范围内。室内相对湿度约为75-90%，室外约为45-75%。最后，通过温度控制，植物室内的生长速率比自然条件下高30%左右。
