Implementation of Smart Agricultural Monitoring System Using Raspberry Pi

Water is the most important factor in increasing agricultural production, so expanding the water system has been a key component of the country's agricultural growth. It is a vital source of life for humans. Water is used in irrigation fields to the tune of 80 percent to 90 percent. Water consumption is increasing as a result of increased globalization and population. Every country faces a challenge in reducing farm water consumption while still providing fresh and nutritious food. In today's world, automation is becoming increasingly vital. It not only keeps you warm, but it also saves you time, money, and energy. In today's world, factories use automation and control devices that are expensive and unsuitable for use in a farm or garden area. Aside from irrigation, the plant must be disease-free. This paper proposes a concept for an automatic irrigation system that will help with water control, intruder detection, and the detection and prevention of plant diseases. By automating soil temperature control, moisture sensing to ensure plants are watered when appropriate, forecast lookup from other weather services, and disease detection and prevention, farmers will be able to irrigate agricultural land more effectively [1]. It makes use of Raspberry Pi 3, Node MCU microcontrollers, Wi-Fi module, relay boards, GSM shield and a few irrigation systems and disease detection sensors, as well as a picture of the plant provided to the pi, which automatically displays information about that crop. The analogue data from the sensors is converted into a digital signal by the node MCU and sent to the Raspberry Pi3 via the Wi-Fi Module. The farmer can access information about the field condition from the server at any time and from any place, saving both manpower and time. The aim of this paper was to keep track of the temperature, humidity, and PH value while also looking for crop diseases.
