Nutri sensor/IOT based soil probe

A soil probe is an electronic device used to measure important soil parameters such as Nitrogen (N), Phosphorus (P), Potassium (K), Electrical Conductivity (EC), pH, soil moisture, and temperature, which are essential for plant growth and maintaining soil fertility. It helps in identifying nutrient levels, improving balanced fertilizer application, increasing crop yield, and reducing the excessive use of fertilizers. The sensor consists of probes or electrodes inserted into the soil, a signal conditioning circuit, a microcontroller, a display/output unit, and a power supply. It works on the principle of electrochemical measurement, where soil nutrients and properties affect electrical characteristics like conductivity, and these changes are converted into accurate readings through calibration. Soil probes are widely used in precision agriculture, soil testing, fertilizer management, and IoT-based smart farming systems because they provide quick, real-time results, are portable, and improve fertilizer efficiency while reducing cost and environmental impact. However, their accuracy depends on soil type and moisture, they require regular calibration, and they cannot completely replace laboratory soil testing.

Pyrolysis Reactor for Thermal Decomposition of Biomass into- Biochar

Biochar unit is designed to convert biomass into biochar through pyrolysis at around 600°C under high pressure for 2–3 hours. It consists of an outer cast iron drum and an inner stainless-steel drum. The outer drum is heated using six coils connected in parallel, insulated with glass wool and covered with a GI sheet to reduce heat loss. The inner drum holds the biomass and is placed between the coils for uniform heating. An oil-free air compressor removes excess air to maintain oxygen-free conditions, while a barometer monitors pressure. Thermocouples and an auto-cut mechanism ensure temperature control, and the entire unit is mounted on a mild steel base with wheels for easy movement.

Automatic Irrigation System (Prototype)

An Automatic Irrigation System is an advanced precision agriculture technology designed to regulate water application to crops through automated monitoring and control mechanisms. The system utilizes soil moisture sensors, climatic inputs, and programmable controllers to determine crop water requirements and initiate irrigation at optimal intervals without manual intervention. By ensuring timely and precise water delivery, it enhances irrigation efficiency, conserves water resources, reduces labour dependency, and promotes uniform crop growth. The technology contributes significantly to sustainable agricultural production by minimizing over-irrigation, improving water use efficiency, and supporting climate-resilient farming practices. Its integration in agricultural education and research also provides practical exposure to modern smart farming and resource management technologies.
