Farm Sensor and Weather Data Pipeline on Delta Lake

Added Jun 2025 3 design docs

Agricultural decisions depend on combining slow-moving data, historical weather records and seasonal yield files, with fast-moving field sensor readings, yet these arrive in different formats on different rhythms. A unified pipeline that treats batch and streaming as one system lets agronomists see current field conditions in the context of history rather than in isolation. The intern creates that unified pipeline on Databricks. Batch ingestion loads CSV and JSON datasets, weather archives and sensor exports, using Spark, while Structured Streaming continuously ingests simulated real-time sensor readings. Both paths write to Delta Lake tables refined through a Medallion Architecture: Bronze preserves raw inputs, Silver standardizes units, timestamps, and sensor identifiers with Python and SQL transformations, and Gold produces analysis-ready aggregates such as daily readings per field joined with weather conditions. Databricks SQL dashboards visualize the curated Gold layer, giving users charted insights into moisture trends, temperature patterns, and anomalies worth investigating. The project teaches the intern how batch and streaming ingestion coexist in one lakehouse, how schema standardization turns messy multi-source data into a coherent model, and how to carry raw files all the way through to dashboards stakeholders can use.

Smart Farm Data Platform with Delta Live Tables Orchestration

Modern farms generate relentless data, soil sensors, weather stations, and drone imagery telemetry, but agronomy teams rarely have engineering support to turn those feeds into trustworthy analytics. The gap is architectural: raw sensor streams need ingestion, validation, transformation, and governance before anyone can responsibly base irrigation or planting decisions on them. The intern designs an end-to-end smart agriculture platform on Databricks and Spark. Sensor and drone data arrive through Kafka streams and Autoloader file ingestion, then flow through a Medallion Architecture implemented with Delta Live Tables: Bronze tables capture raw records, Silver tables apply DLT expectations that quarantine bad readings, and Gold tables aggregate field-level metrics. Databricks Workflows and Airflow orchestrate the pipelines on schedules and dependencies, while Databricks SQL dashboards visualize crop health indicators and yield predictions from the curated layer. The intern applies Unity Catalog for governance, secret scopes for credential handling, and cluster policies aimed at cost control. The project demonstrates command of the modern lakehouse stack, streaming plus batch ingestion, declarative pipelines with enforced data quality, dual orchestration tools, and security practices, applied to a domain where data quality has physical consequences.

Farm Sensor Data Ingestion Pipeline with Kafka and HDFS

Modern farms generate continuous streams of readings for soil moisture, temperature, humidity, and equipment status, but the raw numbers are useless until they are reliably collected, stored, and summarized. Agritech companies solve this with streaming data platforms, and this project introduces that architecture at a scale a newcomer can build end to end. The intern writes Python producers that simulate realistic agricultural sensor streams and publish them to Kafka topics, then builds consumers that read the streams, validate and enrich the readings, and land them in HDFS for durable, distributed storage. On top of the stored data, Python analysis scripts compute aggregates such as average soil moisture per field, daily temperature ranges, and gaps that indicate sensor failures, producing summary files a farm manager could act on. The focus stays on the pipeline itself: partitioning topics sensibly, handling malformed messages, and organizing HDFS directories for easy downstream analysis. Through this big-data project the intern gains a concrete understanding of publish-subscribe streaming, distributed file storage, and pipeline design, which are foundational skills for any data engineering role.

Distributed Crop Yield Analysis Pipeline with PySpark

Predicting and improving crop yields starts with unglamorous plumbing: field sensor readings and harvest records must be collected reliably, stored at scale, and distilled into trends a agronomist can act on. This project has the intern build that plumbing with the same tools used in commercial agritech data platforms. Simulated sensor and yield data is streamed through Kafka, capturing the continuous, event-driven nature of readings arriving from many fields. The stream lands in HDFS, which provides distributed storage for the growing dataset. PySpark batch jobs then process the records to generate yield summaries by crop and region, seasonal trend reports, and comparisons across growing conditions. Python scripts coordinate the workflow end to end, from ingestion through processing to exporting results as clean data files. The project is deliberately data-focused, with all outputs delivered as files and reports rather than interfaces. By completing it, the intern learns the streaming-to-batch architecture at the heart of big-data engineering, gains real PySpark experience with joins, aggregations, and window-style analysis, and can speak concretely about applying data infrastructure to agricultural problems.
