However, the Indian agricultural sector is facing several challenges such as inefficient water usage, poor soil quality, and unpredictable weather conditions, which directly impact crop yield and profitability. In recent years, there has been an increasing demand for smart agriculture systems that can help farmers optimize their crop yield and reduce resource wastage [1]. In this paper, we propose an IoT-based smart agriculture robotic system that is designed to sense the temperature, humidity, and moisture levels in the soil, and transmit this data to an IoT platform via the internet. The system is also equipped with wireless and manual control capabilities via a mobile application using Bluetooth, enabling farmers to control the movements of the robotic system in real-time. Compared to the complex and expensive smart agriculture systems currently on the market, our proposed system is both cost-effective and easy to use. This allows farmers to optimize resource usage and reduce waste, and take corrective measures to prevent crop loss when soil moisture falls below a predetermined threshold. The system's rechargeable lithium-ion batteries offer a cost- effective and sustainable power supply solution, especially in rural areas with limited access to reliable electricity. Overall, this system has the potential to improve crop yield and profitability while reducing resource waste and environmental damage in the agricultural sector of India. Keywords— Smart Agriculture system, Internet of Things (IoT), Robotic Car, Mobile application, Bluetooth The agriculture sector is one of the most important sectors in India, as it provides livelihoods for a significant portion of the population and contributes significantly to the country's economy. However, the sector faces several challenges, including water scarcity, inadequate irrigation, and a lack of real-time monitoring and control systems. In order to address these challenges, there is a need for innovative and cost-effective solutions that can enable farmers to optimize resource usage and increase crop yields. The need to increase farm productivity has become urgent due to factors such as the exponential expansion of the global population, which would require the globe to produce 70% more food by 2050(according to the UN Food and Agriculture Organization), shrinking agricultural lands, and depletion of finite natural resources, the need to enhance farm yield has become critical. The problem has been made worse by the limited supply of natural resources including fresh water and arable land as well as declining yield patterns in a number of essential crops. The agricultural workforce's changing organizational structure is another hindering factor. In addition, agricultural work has decreased in the majority of the nations. The demand for physical labour has decreased as a result of the shrinking agricultural workforce, which has prompted the introduction of internet connectivity solutions in farming techniques. The traditional farming methods are no longer efficient and cannot meet the increasing demand for food production. The agricultural sector needs to modernize and embrace technology to meet the challenges.
