The Science Inside AirCal.

Discover the high-precision hardware, AI-powered intelligence, and open-source philosophy that sets our sensors apart.

A Single Sensor for a Complex World.

Our core mission is to provide a unified, reliable solution. The AirCal sensor is engineered as a single sensor solution for multi-environment particulate pollution monitoring, from a quiet home to a busy urban intersection. Its high-precision laser scattering module provides real-time data for PM_1.0, PM_2.5, and PM₁₀.

The AI Engine: Consistency Across the Globe.

Air is not a constant. Temperature and humidity can skew a sensor's readings. Our solution is an onboard AI-enabled local environmental fluctuations compensation model. This custom neural network analyzes environmental data in real-time, correcting for drift and ensuring our readings are accurate and consistent, whether you're in humid Mumbai or dry Denver.

Sensor Data: Before & After AI

This chart demonstrates how our AI model smooths out fluctuations caused by environmental factors, providing a more accurate and stable reading.

Radically Open. Built for Trust.

We believe in transparency. Our platform is built on two open-source pillars:

Open Source Hardware

Our hardware designs and schematics are publicly available. We invite researchers, students, and enthusiasts to inspect, learn from, and even help us improve our technology. No black boxes.
