The creation and use of sensing technology is one of the chief components in achieving sustainability in agricultural production through precision agriculture. This article outlines the primary sensing methodologies used for tracking soil nutrients in opinion of recent improvements in the sensing devices utilized in literature. To locate the macro-nutrients in the soil, the designed prototype has AS73211 color sensors that work with a NODE MCU. Two comparative soil sample scrutiny were used for the measurement. Testing on various samples showed that Nitrogen Phosphorous and Potassium is more that the threshold values of 445-485nm, 505-565 and 625 – 685nm respectively in both the soil samples. The method developed is more useful and suitable for use in farming.
