Fleet Vehicle Emissions Sensor Log

This dataset provides granular, real-time emissions logs from smart sensors installed on fleet vehicles, including CO2, NOx, and PM readings, vehicle details, geolocation, and regulatory compliance flags. It enables transportation managers to monitor sustainability, optimize maintenance, and ensure regulatory compliance, supporting ESG and operational reporting across diverse fleets.

Behind this dataset

Same schema. As many rows as you need.

These 120 rows came out of a blueprint — 18 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with

Each row represents one sensor reading per vehicle per day.
Emission values are recorded in grams CO2/km.
Readings must include timestamp, vehicle ID, location, and sensor integrity status.
Flag readings exceeding regulatory thresholds for review.
Vehicles with missing data for over 3 days are marked for maintenance.
