A study was conducted to develop the sensor and evaluate the soil moisture by using soil moisture sensors and to establish the relationships between soil moisture content and electrical resistance value. Study involved the fabrication of the soil moisture probes, automation network and laboratory testing of automation system. The soil moisture sensor and automation system used for experiment were developed at Department of Soil and Water Engineering, Tamil Nadu Agricultural University, Coimbatore. System is tested and calibrated for automatic irrigation scheduling. Laboratory test programmes were conducted for the performance of the soil moisture sensor in salt solution and different soils and to develop the calibration curve. It was observed that a significant logarithmic relation between electrical conductivity and resistive value of sensor-1, sensor-2, sensor-3 and sensor-4 with an R2 value of 0.95, 0.96, 0.96 and 0.96, respectively and with mean values of electrical resistance found R2 value of 0.964. Because of the sensors were tested for wide range of electrical conductivities ranges 0.01 dSm-1 to 8.12 dSm-1. Soil moisture sensor was evaluated with respect to the moisture content of the black soil and it was predicted that the electrical resistance in the range 197 Ohms to 260 Ohms at an average of 224 Ohms at average soil moisture content 58.51 per cent. And at the range of 410 Ohms to 511 Ohms at an average 468 Ohms at 32.41 per cent on 75 hours during the experiment. It was observed that average moisture content 58.51, 57.01, 55.08, 52.73, 50.63, 48.48, 46.16, 42.01, 39.68, 37.26, 34.73 and 32.41 per cent recorded at an average duration of 0, 3, 6, 18, 24, 27, 45, 48, 51, 69, 72 and 75 hours, respectively.Keywords
