The increase of salinity in the soil and water bodies which simultaneously declines the productivity of plants is of great concern to agriculture in Nigeria and the world at large. However, for effective and timely regulation of salinity, a proper measurement is required. The microcontroller unit (MCU) was programmed by micro-basic structural language displaying 8-bit binary values in analogue digital converter (ADC) I6 characters per line form. The hardware, software and power supply sub-systems were basic parts of the system design. The design and development of an in-situ salinometer proved efficient with the instant resulting of salinity values for soil and water samples with two (2) each – samples A and B. The salinity results of the four samples were 640 mg/l and 5760 mg/l (soil samples) and 640 mg/l and 5120 mg/l (water samples) indicating low salinity and moderate salinity respectively. The result of this work could be adopted and applied in the agricultural sector in measuring the salinity and conductivity of different soil and water samples with 90 % efficiency. The percentage rating is directly proportional to efficiency, voltage and resistivity
