MT-AIR-07 · Air Quality

Indoor and outdoor.
One AQI, one stack.

LIVE·32 stations · city AQI 138 · 2 episodes active

Laser PM, NDIR CO₂, electrochemical NO₂ / O₃ / NOx and met instruments — outdoor poles, indoor walls and battery wireless pucks on one stack. Episode detection, source attribution and a public AQI widget the city's citizens can actually read. The honest version of the air-quality argument.

§01 — What this is

Most cities have one AQI number for the whole map. Yours should have one per kilometre.

01

Indoor + outdoor · one stack

Same data model from a classroom CO₂ puck to a roadside NOx pole. Same Sensoverse instance hosts both. The smart-city map and the building DCV controller share their data without an integration project.

02

Episode detection · not averages

We flag episode boundaries — where a plume starts, where it drifts, where it falls below threshold. Source attribution falls out from wind data + station chemistry. Citizens get a useful map; regulators get a useful audit trail.

03

Built to last outdoors

Outdoor stations are IP65, solar + battery, with electrochemical cells on an annual change schedule. Pole, gantry or perimeter mount. Two-year hardware warranty; five-year build life.

§01 — Complete stack

End-to-end. Not just a device.

A solution is hardware in the field plus the infrastructure that makes the data useful — secure ingestion, a dashboard your team actually opens, and APIs to whatever runs your business.

§03 — Where it goes

Eight applications. One AQI.

Pick a row — see what we monitor there.

01 / 08 · Outdoor stations

Smart-city · 32 stations · 12 km²

Solar-powered outdoor stations with PM1/2.5/10, NO₂, O₃, NOx, CO and meteorology. LoRaWAN uplink, IP65 housing. Forms the AQI map a city publishes to citizens, with episode-level audit trail.

§04 — Why not handheld + monthly

A handheld PM reader is a snapshot. The plume doesn't wait for monthly.

Most city air-quality data comes from a handful of CPCB reference stations and the occasional municipal handheld survey. Episodes start and end between readings. Dense low-cost meshes — calibrated against the reference network — fill the map, catch the plume and tag the source.

§04 — Security & infrastructure

Built for plant & campus IT.

Industrial sites have non-negotiables — segmentation, audit trails, and the ability to run when the WAN drops. We design for that on day one.

Transport
TLS 1.3 device → cloud. Mutual auth via X.509 or pre-shared keys. LoRaWAN 1.0.4 / NB-IoT carrier-grade encryption end-to-end.
Identity
Per-device certificates, automated rotation. RBAC + SSO (SAML / OIDC). Audit log of every operator action.
Data
AES-256 at rest. Tenant isolation at row + schema level. Configurable retention, GDPR / DPDP-aware exports and deletes.
OTA & ops
Signed firmware, staged rollouts, rollback. 24×7 monitoring, on-call, runbooks. SLA up to 99.95%.
Deploy
Sensoverse Cloud (default), private VPC, on-prem (air-gapped), or hybrid. Mumbai & Dubai regions.
Compliance
ISO 27001 controls, SOC 2 Type II in progress. Vendor / penetration test reports under NDA.
