[Audio] Feasibility And Viability Feasibility Working prototype: ~₹4000–₹7500 Uses easily available, low cost electronic components E-S-P-3-2 provides sufficient processing power and Wi Fi connectivity Modular sensors make the system easy to assemble and maintain Prototype can be tested on small agricultural plots Challenges / Risks Sensor calibration and accuracy Outdoor weather and moisture can affect sensors Wi Fi availability may vary Pump and power requirements must be managed properly Mitigation To solve these challenges, first, we will set the sensors according to the soil type. We will protect the sensors from rain and outdoor conditions. We will use a stable power supply for the system. We will also set proper limits so that the pump works safely And finally, we will make the sensors easy to replace if there is any problem..
