HighlightsA measurement device for droplet mass deposit was improved to enhance its performance.A wireless data transmission system was used to achieve convenient data sharing.A user interface was designed for display and analysis of the measurement results.A positioning mechanism was designed for arranging measurement devices promptly.Abstract. Measurement of droplet mass deposit is important in spray research and spray performance evaluation. In this article, an online measurement device for droplet mass deposit was improved based on the original design. The measurement resolution, precision, and data stability were improved by optimization of the structure and components and by data filtering. The resolution reached 0.00067 mg cm-2. Comparison tests showed that the relative error between the original device and an analytical balance was 6.68% to 8.48%, and the relative error between the improved device and the analytical balance was 5.24% to 6.15%. Compared with the original device, the relative error decreased and the precision improved. The relative error between the improved device and a tracer method was 5.11% to 6.99%, and the precision of the improved device was close to that of the tracer method. A positioning mechanism was designed to arrange measurement devices promptly in the test area, and a wireless data transmission system was used to achieve convenient data sharing. A user interface was designed to display the results in the form of tables and contour maps. Tests were conducted to measure the droplet mass deposit distribution of one nozzle, the droplet mass deposit distribution in a tree canopy, and the uniformity of the droplet mass deposit distribution in a small horizontal area. The results showed that the improved measurement device could provide data promptly and conveniently for spray research and spray performance evaluation.

Data Transmission System

Lightning is an environmental phenomena that cause many fatalities and property destructions in Malaysia since the country is located in the high isokeraunic area. To reduce the fatalities an alert system should be developed. The alert system can consist of several Rotating Electric Field Mill sensors which are installed in spread. Data from the sensors must be gathered in a data centre building for observation,  analysis, and triggering an alert signal. Therefore, the objective of this work is to develop a data transmission system by using a wireless method. The wireless data transmission system consists of a microcontroller, voltage divider, and GSM module. Hardware and software development is carried out to achieve the objective. Furthermore, to test the transmission system a function generator is connected to the analog digital converter input of the microcontroller. By varying the magnitude of the function generator output an observation on data transmission is carried out. It is found that the magnitude of receiving data which is displayed on the website is exactly the same with the sent data. In here in lab wireless data transmission system devices and a website to observe the transmitted data from Rotating Electric Field Mill sensors has been successfully developed.

The purpose of this study was to introduce the design and realization about a measurement system, which is based by accelerometer ADXLl05 and wireless data-transmission module for starting line of athlete’s reaction time. This system plotted curves of players’ reaction time using 89C205l as the core of the front-end of the system reaction time measurement device, the measurement device take real-time captures players' reaction time, and then sent over the wireless data-transmission module player reaction time to the PC machine to display, and to record the reaction time.
