This article aims to a spraying robot controlled by application smartphone for pepper farm. Promoting agricultural technology by developing agricultural tools and to help farmers reduce the use of labor in agriculture. Reduce direct chemical exposure from traditional chemical, which was very harmful to the body. The result of their testing for the spraying robot controlled by application smartphone: 1) the testing a Bluetooth signal connection for spraying robot can connected to a constant Bluetooth signal at a distance of up to 50 meters 2) the testing a WiFi signal connection can connected to a constant WiFi signal at a distance of up to 120 meters and 3) the testing power supply 24VDC from battery for spraying robot working continuously at time period 0-90 minutes per full charging in working area about 1,600 square meters, which was speed moving at 5 kilometers per hour. The 30 pepper farmers who have tested the spraying robot for pepper farm were satisfied on this spraying robot at 4.31 was at a high level. Therefore, the results from the testing of the spraying robot. With the usage of modern agricultural technology, farmers can be more comfortable in their careers and be safe from various chemical spray drift.

NO 2 gas Sensing characteristics of thin films of Zinc oxide obtained by spray pyrolysis were studied. The film thickness was about 550nm. The effect of indium doping on the sensor performance were also studied. The sensing behavior in the temperature range of 100–225°C was measured to find out the optimal working temperature.

Three different structures SnO/sub 2/, SnO/sub 2//Ag and Ag/SnO/sub 2/ on glass substrates were performed. The SnO/sub 2/ and Ag films were deposited by the chemical spray technique (spray pyrolysis), and vacuum evaporation, respectively. In this work the films sensitivity in a propane atmosphere, C/sub 3/H/sub 8/, at different operation temperatures are reported. According to our results the SnO/sub 2//Ag structure showed the highest sensitivity.

Nuclear environmental equipment qualification is used to insure equipment operability at an end of life condition following a design basis event. The environmental effects must be accounted for when making this determination. One aspect of the design basis event is chemical spray which is applied to mitigate the accident. The corrosive effects of typical containment sprays upon insulation systems commonly encountered in containment components are examined. Comparison methods to use when evaluating adequacy of equipment test data are discussed and examples of these analysis techniques are given.
