An instrument to measure the parameters of water (pH, Turbidity, Conductivity, Dissolved Oxygen, Temperature and Depth) that determine quality of river water was developed and used to measure river Niger water quality parameters in New Bussa as good quality river water is important for wellbeing and long life span of aquatic animals. Arduinomega 2560 Microcontroller with 256kB internal memory was connected to the sensors and RTC. The 15 watt, 12 V solar panel supplied DC to LM7805 linear regulator used to supply the required 5V for the microcontroller and the sensors. The data was displayed on 16 by 4 LCD and logged on SD card. It was also programmed in C++ to transmit the logged data through GPRS module to remote phone used to monitor the instrument after calibration. The instrument was suspended with Styrofoam on river Niger and hooked down to the waterbed with rope and heavy stone. Two measurements were done at two inlet and outlet sites of river Niger in New Bussa, Niger state The dissolved Oxygen, pH and Temperature values 6.4 mg/L, 7.3 and 28.5oC measured were similar for the two sites while Conductivity, Turbidity values differences were less than 0.4. However the inlet depth was 35.4m while the outlet depth was 46.5m. The measured river water parameter data were compared with USEPA, WHO and ICMR standards and are within approved limit for general freshwater aquatic life.
