Project Description: AutoBotanic is a smart soil management system that consists of two parts. The first part is the soil health
monitoring system, which includes a transmission tower connected to several sensors, such as an NPK sensor
that monitors the levels of nitrogen, potassium, and phosphorus in the soil. It also has a soil temperature and
moisture sensor capable of providing accurate values. The entire transmission tower is powered by a self-adjusting
solar panel that can adjust its direction toward the sun. These sensors are connected to a custom-designed transmission
PCB, created by me using open-source designing software. I ordered this PCB from an Indian manufacturer, which keeps
the production cost low. The PCB features an Arduino Nano as the main microcontroller, connected to a high-range NRF
module that transmits the soil's nutritional values. These signals are received by the receiving module, which contains
an ESP32 that uploads the values to the internet, allowing them to be observed via an app or website.
The second part of the project is the smart fertilizer dispenser. As we saw, the soil health monitoring system accurately
detects deficiencies in the soil, but how can these deficiencies be addressed? This is where the smart fertilizer dispenser
comes into play. This technology is so unexplored that I can even patent it, and I have already started the process of patenting
it. The smart fertilizer dispenser reads the values from the NPK sensor and then begins dispensing fertilizers from its three
containers, each containing nitrogen, phosphorus, and potassium, until the values reach the desired threshold. For example
, if a farmer wants to grow wheat, they can set the dispenser to wheat mode through the AutoBotanic website. This will adjust
the threshold values of nitrogen, potassium, and phosphorus to match the specific needs of wheat.
