The Development of portable Dataloger for students

本研究实现的功能和发现(1)装置外壳由增强树脂制成，尺寸为90 × 135 × 34mm。第一个目标是判断，只要使用一般能够获得的部件，即使假设80 × 120 × 20mm或更小，也不可能实现更小的小型化。此外，虽然由于成本巨大，但由于塑造一个特例而放弃了实现目标的可能性。(2)使用两节AA碱干电池可连续工作2.5小时以上。通过对未来节电措施的制定，可以预期运行5小时以上。(3)实现了温度、湿度、照度、紫外线强度、ph值、Nox、简单比色计、辐射剂量、定时器、计数器等测量功能。其中，温度、紫外线强度、照度、计时器、计数器和秒表都被假定为内置的主体。(4)显示采用16 × 2线反射式LCD。当显示器的形状和尺寸使设备小型化时，这就成为一个重要的因素。(5)为提高操作操作性，省去了图形键，并尝试通过菜单选择方法和日语引导功能进行简化。结果，操作键变成了7。(6)通过红外线通信实现了个人电脑与打印机的协同工作。因此，可移植性和可操作性得到了改善。(7)编写了汽车尾气亮度、空气污染、辐射、食物、房间、健康、紫外线、生物、酸雨等相关教材。(8)对于教材基础数据的有效收集，本装置作为对使用这些教材的班级所获得的评价进行了明确。

Function achieved by this research and development and obtained finding(1) The case of the device became 90 × 135 × 34mm made of a reinforced resin. A first target was judged that the miniaturization more than this was impossible as long as parts which were able to be obtained in general were used though assumed 80 × 120 × 20mm or less. Moreover, the possibility of accomplishment of a goal was abandoned by molding a special case though was because became great cost amount.(2) Continuous operation for 2.5 hours or more was achieved with two AA alkali dry batteries.Operation for five hours or more can be expected by measures of making to the power saving in the future.(3) A temperature, humidity, an illuminance, ultraviolet rays strength, ph, Nox, simple colorimeter, and doses of radiation, the timer, and the counter were achieved as a measurement function. The temperature, ultraviolet rays strength, the illuminance, the timer, the counter, and the stop watch were assumed with built-in the main body among these.(4) The display adopts reflection type LCD of 16 × 2 lines. became an important factor when shape and the size of the display miniaturized the device.(5) The figure key was omitted for the operativeness improvement, and tried for the simplification by the menu selection method and the Japanese guidance function. As a result, the operation key became seven.(6) The cooperation of the personal computer and the printer was achieved by the infrared rays communication. As a result, portability and operativeness have improved.(7) The brightness of the exhaust gas of the car, air pollution, the radiation, food, and the room, health, and ultraviolet rays, the living thing, and acid rain, etc. were developed as a related teaching material.(8) Effective to the collection of basic data for the teaching material this device as the evaluation which had been obtained because of the class which used these teaching materials was clarified.
