Low cost data acquisition and logger system for monitoring waste water is introduced. The proposed circuit is simple by using one-chip microcontroller. A portable RAM card of the proposed system makes it simple to acquire the monitored data. Serial communication is adopted to communicate with remote monitoring computer. CSMA\CD, which is used widely as MAC(Medium Access Control) in ethernet, is modified to apply a RS485 serial communication. The proposed system acquires the information of the waste water by using the presented data acquisition and logger system. The monitoring data of water quality is stored in the database to analyze the factor and progress of water pollution.
