| Abstract: | To produce a measuring system for monitoring temperature and humidity in green-house at low cost based on unibus thermometer sensor, focused on characteristic of digital thermometer DS18B20. To design the basic flow chart in C language and Serial communication procedure in Visual Basic 6.0. The system is proved effective at automatic data acquisition, dynamic display, store and print of monitor data. The system characterizes its advantage for it low cost in design, use and maintenance. |
