Continuous monitoring of environmental parameters is necessary in order to achieve maximum plant growth in a greenhouse system. The aim of this study is to perform a real time data monitoring from multiple sensors in greenhouse using Arduino and Excel add-ins. DHT22 sensors, BH1750 sensor are the main sensors used in this study which give the exact value of temperature, humidity, and light intensity, respectively. Arduino Uno board provides multiple inputs analogs and I/O digitals were utilized to read the data sensor aforementioned that applied for the greenhouse. The level of accuracy of each sensor was compare to the standard device results. The results show that the accuracy of the sensors measurement is very good. This system design is real time, simple and low cost that given ability for user to monitor, collect, and to plot their greenhouse environments data in an Excel sheet.

Automatic sprinklers using a soil moisture sensor is formed based on microcontroller technology. The hard- and software system were designed to adapt the greenhouse prototype. The sensors were calibrated by comparing the value with the standard instruments. Observations were conducted on the kale seedsand it monitored for seven days. Based on the observation result, the sensorsable tomeasure temperature, humidity, light intensity, and soil moisture in the greenhouse. The automatic sprinkle pumped the water according to the values of soil moisture sensor. The values of those sensors have been delivered to webserver and android application. Moreover, the system is able to grow the kale plant in the greenhouseprototypevery well.

This study develops bio-nano composite gelatin-based edible film (NEF) by combining nanogelatin, cellulose nanocrystal (CNC), and nanopropolis (NP) fillers to improve the resulting film characteristics. The NEF was characterized in terms of thickness, swelling, pH, water content, solubility, vapor and oxygen permeability, mechanical properties, heat resistance, morphology, transparency, and color. The results showed that the thickness and swelling increased significantly, whilst the pH did not significantly differ in each treatment. The water content and the water solubility also showed no significant changes with loadings of both fillers. At the same time, vapor and oxygen permeability decreased with addition of the fillers but were not significantly affected by the loading amounts. The heat resistance properties increased with the filler addition. Tensile strength and Young’s modulus increased for the films loaded with >3% CNC. The elongation at break showed a significant difference together with transparency and color change. The greater the CNC concentration and NP loading were, the darker the resulting transparency and the color of the NEF. Overall results show a considerable improvement in the properties of the resulting NEFs with the incorporation of CNC and NP fillers.
