Live mesh • Hedera-anchored

Breathe the
data behind your air

An intelligent sensor mesh that monitors air quality in real time — PM2.5, PM10, CO₂, temperature and humidity — with live map visualization and tamper-proof readings.

Air-quality index

A color you can read at a glance

Every node maps to the standard AQI scale, so anyone can understand the air around them in a second.

0–50

Good

Air quality is satisfactory; little or no risk.

51–100

Moderate

Acceptable, but unusually sensitive people take note.

101–150

Sensitive

Sensitive groups may feel mild effects.

151–200

Unhealthy

Everyone may begin to experience effects.

201–300

Very Unhealthy

Health alert; serious effects for everyone.

301+

Hazardous

Emergency conditions; avoid outdoor activity.

Why a mesh

Monitor air quality, grow city-level coverage

Deploy sensor nodes, stream real-time data and visualize the mesh on an interactive map.

Mesh coverage & open API

Smart Air-Quality Mesh is a connected network of smart sensor nodes that continuously monitor key indicators such as PM2.5, PM10, CO₂, temperature and humidity across many locations. Each node communicates within a distributed mesh, so real-time environmental data keeps flowing even where connectivity is limited. Built on open-access principles and integrated with the Hedera Hashgraph network, it guarantees data transparency, immutability and accessibility.

Real-time monitoring

The system continuously measures PM2.5 and PM10 — fine and coarse particulate matter that can penetrate the respiratory system and impact human health. Monitoring these particles gives critical insight into pollution from traffic, industry and environmental conditions. CO₂ concentrations are also tracked to evaluate ventilation efficiency and detect areas with poor circulation or harmful buildup, indoors and out.

Insights

Insights dashboard

Everything you need to read the air — readings, maps, reports and alerts in one place.

Air-quality dashboard with charts and node status

  • Live sensor readings

    Track PM2.5, PM10, CO₂, temperature and humidity in real time across the mesh.

  • Interactive map

    Visualize nodes on a city map, filter by area or pollutant and check node status instantly.

  • Reports & alerts

    Generate downloadable reports, set thresholds and get alerts when pollution exceeds safe limits.

On-chain proofs

Publish sensor readings to Hedera

Anchor sensor readings on Hedera Hashgraph for immutable verification. Compute a SHA-256 proof locally, then publish a compact proof (node_id, ts, hash) via your backend to a Hedera HCS topic.

Hedera Proof Publisher
Compute → Sign (server) → Anchor
How it works
  • Client computes a SHA-256 digest of the reading (stable JSON).
  • Client POSTs { node_id, ts, hash } to /api/hedera/publish.
  • Server (secure) signs and submits the small message to a Hedera HCS topic.
  • Server returns topicId and transactionId for verification.
