| Abstract |
A Development of a data logger for monitoring wasted water is introduced. A characteristics of the system with microcontroller are simple and cheaper. A portable RAM card is consisted for saving a monitored data. Serial communication is adopted to communicate with a remote monitoring computer. CSMA\CD, which is used widely as MAC(Medium Access Control) in ethernet, is modified to apply a RS485 serial communication. When the measured values run over a limit values, the data logger takes alarm. |
