The Portable Agricultural Soil Analyzer, developed by BDTronics, is a field-ready, smart soil testing solution with full Bengali language support. It can instantly analyze soil nutrient  N(nitrogen), P(phosphorus), K(potassium),  PH, Conductivity (EC), Temperature, Humidity (Moisture) directly from the field and provides fertilizer recommendation compatible with DAE (Department of Agriculture Extension, Bangladesh). With AI Powered recommendation engine, the system provides a accurate estimation of the required fertilizer in the soil.

The system combines soil sensing technology, GPS-based automatic soil type detection, location tracking, cloud connectivity, and artificial intelligence (AI) to deliver accurate, location-specific fertilizer recommendations in Bengali, with on-screen display and instant print support.

This handheld device from BDTronics enables real-time measurement of essential soil parameters and transforms raw sensor data into easy-to-understand, actionable insights aligned with Bangladesh Ministry of Agriculture and DAE standards.

Functional Overview:

The BDTronics AI & GPS Based Smart Soil Analyzer is designed as an end-to-end field intelligence system that converts raw soil measurements into practical fertilizer decisions. Rather than focusing on individual components, the system operates as a coordinated workflow where sensing, location awareness, cloud intelligence, and AI-driven interpretation work together seamlessly.

Integrated Soil Intelligence

The device performs multi-parameter soil assessment in a single field operation. It captures essential soil fertility and condition indicators and automatically interprets them against nationally approved agronomic benchmarks. This ensures that results are not just numerical readings, but meaningful indicators of soil health and nutrient availability.

Location-Aware Analysis

Combined with GPS-based location tracking system, the device automatically detects the soil type (Sandy/ Silt/ Loam/ Silty Loam etc) such as each soil test is contextually linked to its exact geographic position, which provides more accurate result. This allows the system to factor in regional soil characteristics, agro-ecological zones, and historical patterns when generating recommendations. The result is fertilizer guidance that is specific to the land, not generic to the crop.

Cloud-Connected Decision Engine

All collected data is securely transmitted to a centralized cloud platform where classification, validation, and analysis take place. Cloud processing enables:

• Consistent application of Ministry of Agriculture and DAE standards

• Centralized model updates without device replacement

• Scalable deployment across districts, upazilas, and unions

This architecture ensures uniform quality of recommendations regardless of where the device is used.

AI-Powered Recommendation System

At the core of the system is a proprietary AI recommendation engine trained on official fertilizer guidelines, soil fertility data, and agronomic rules relevant to Bangladesh. The AI evaluates nutrient balance, soil condition, and location context to calculate precise fertilizer requirements.

To enhance usability, AI-generated results are refined into clear, farmer-friendly explanations, removing technical complexity while preserving scientific accuracy.

Farmer-Centric User Experience

The device is designed for practical field use with minimal training:

• Step-by-step guided operation on a touch interface

• Fully localized Bengali language support

• Clear visual summaries instead of raw technical data

This ensures accessibility for farmers, extension officers, and field technicians alike.

Instant Results & Documentation

Once analysis is complete, results are delivered instantly on-screen and can be printed on demand. The printed output serves as:

• A physical advisory for farmers

• A record for extension services

• A reference for follow-up soil management decisions

This bridges digital analysis with real-world agricultural workflows.

Reliable Field Operation

The system continuously monitors power, connectivity, and operational status to maintain reliability in rural environments. Portable power options and optional solar support allow uninterrupted use in off-grid locations, making the device suitable for widespread field deployment.

Smart Solar Charging System

The integrated solar-powered charging system allows the device to be charged directly in the field, eliminating concerns about power availability for charging the device. This ensures uninterrupted operation during outdoor use, making the system ideal for remote agricultural locations where access to grid electricity is limited or unavailable. The smart power management design optimizes charging efficiency and battery health, enabling reliable, long-duration field performance.

Scalable Agricultural Platform

Beyond individual soil tests, the BDTronics solution functions as a scalable agricultural data platform. Aggregated soil and location data can support:

• Regional soil fertility mapping

• Policy and planning insights

• Long-term soil health monitoring

The BDTronics AI & GPS Based Smart Soil Analyzer is not just a testing device—it is a decision-support system for precision agriculture. By unifying real-time sensing, location intelligence, government-aligned standards, and AI-driven interpretation, it empowers faster, smarter, and more sustainable fertilizer management at the grassroots level in Bangladesh.

Our AI and GPS Based Real-Time Handheld Soil Analyzer with Printing Function represents a modern, intelligent, and practical solution for improving soil health assessment and fertilizer management at the field level. By combining real-time soil sensing, GPS-based location identification, cloud connectivity, and AI-driven analysis, the system transforms complex soil data into clear, actionable recommendations in Bengali, making it accessible to farmers and extension workers alike.

The integration of automated data classification based on Ministry of Agriculture and DAE standards ensures reliability and consistency, while the AI-powered recommendation engine enhances accuracy and usability through human-friendly explanations.

Overall, our solution enables faster decision-making, reduces dependency on laboratory testing, promotes balanced fertilizer use, and supports sustainable agricultural practices.
