An Automatic Aeroponics Growth System Based on Ultrasonic Atomization

Abstract:

An automatic aeroponics growth system is developed in this paper on the base of ultrasonic atomization which has more advantages to product nutrient mist compared with other traditional atomizing type. The system is mainly consist of two parts including the aeroponics culture mechanism and automatic control device. The structure of the growth system and its working principle are introduced in detail, and its components, software and hardware designing are given in the paper. In order to improve atomization efficiency of nutrient solution for uniform nutriment absorption at the root system, the ultrasonic atomizer, which can atomize the nutrient solution to the ultrafine particles of 1-5 microns diameter, is employed as the key component of system. Considering the effects of temperature and humidity on plant root growth, a digital temperature-humidity sensor is used to detect the environmental signal of the plant root system . The temperature and humidity information can be transmitted to MCU which automatically controls the actuators to adjust the temperature and humidity of nutrient mist in a expected range. The system with features of simple structure and convenient control can supply a experimental platform which is not only comfortable for aeroponics culture, but also convenient for morphologic observation of plant roots.
