Abstract

The basic idea behind the project to is optimize the overall crop yield through systematic layout planning of field and
utilizing nutrient sensor. The field is dividing into “n” grids that consist of a sensor embedded into the soil in each. Each
sensor consists of a thermocouple that is connected to a LED circuit. When fertilizers and water are introduced due to the
following exothermic reaction, the circuit breaks. This is denoted by a green LED light (binary 0). Counter-wise, if the
nutrient reactions are not strong enough to send the voltage required to break the circuit, the LED glows red (binary 1)
This signals are relayed using GSM modem and ZIGBEE protocol to the motor which consists of receiver, transmitter and
relay signal processor. Then processor deploys water and nutrients required per grid according to this analysis.

Water wastage and over-utilization of fertilizer is avoided, thereby increasing crop yield.
