Ambient Air Quality Monitor

Prana Air uses five distinct sensor technologies — Laser, Electrochemical, NDIR optical, PID, and metal-oxide — all cross-verified against each other within the same device. Prana Air's ambient monitors have been validated against Beta Attenuation Monitors (BAM) — the reference-grade instruments used by CPCB at official government monitoring stations and considered the gold standard for ambient air quality measurement in India. Beyond BAM correlation, the monitors have been independently studied and tested by NEERI (National Environmental Engineering Research Institute) and IIIT Hyderabad — two of the most credible scientific bodies for air quality research in India. This level of third-party scientific validation is extremely rare among low-cost ambient monitoring solutions and gives clients a strong basis for trusting the data in both compliance and research contexts.

Prana Air provides initial factory calibration for all units, with calibration certificates available on request. For CAAQMS installations, Prana Air's technical team supports on-site zero-span calibration and multipoint calibration against certified reference gases. For the Ambient PM and Prana Sense models, Prana Air offers remote firmware-assisted calibration corrections and scheduled servicing. It is generally recommended to recalibrate ambient monitors every 6 to 12 months depending on the deployment environment and the regulatory requirements of the site.

Most low-cost air quality devices rely on a single sensor type with no compensation for environmental variables like relative humidity, temperature fluctuations, or cross-gas interference — all of which cause major reading errors outdoors. Prana Air addresses this through five cross-verified sensor technologies within a single device, dual PM sensor inlets for internal validation, built-in temperature and humidity compensation algorithms, multi-parameter sensor fusion, and cloud-side data correction using proprietary AQI.IN algorithms. The result is a device that has been validated against BAM reference monitors and independently studied by NEERI and IIT Hyderabad — institutions that set the benchmark for air quality science in India.

Yes. Prana Air's ambient monitors feature an IP68-rated weatherproof housing — the highest standard for dust and water ingress protection. IP68 means the device is fully sealed against dust entry and can withstand continuous water exposure, making it suitable for deployment in rain, fog, monsoon humidity, and dusty construction environments without any degradation in sensor performance or electronics.

Yes. Prana Air's Ambient Prana Sense model includes a built-in GPS antenna that automatically tags each data point with precise geographic coordinates. This is particularly important for construction sites and smart city deployments where the exact location of the monitor must be verified and recorded for regulatory submissions.

Prana Air addresses connectivity failures through dual-layer local storage: each monitor has a Micro SD card slot that continuously stores data offline at the device level. If the GSM or Wi-Fi connection drops, the monitor keeps logging data locally without interruption. Once connectivity is restored, the device syncs all offline data to the AQI.IN cloud automatically — ensuring a gapless data record with zero manual intervention. This is critical for regulatory compliance where uninterrupted data continuity is mandatory.

AQI.IN is Prana Air’s proprietary air quality intelligence platform and one of the world’s most visited air quality data platforms, developed and operated by Prana Air Pvt. Ltd.It serves as the central data ecosystem for all Prana Air ambient monitor deployments. When a monitor transmits data via Wi-Fi, GSM, or RS-485, that data flows into the AQI.IN cloud where it is processed, stored, and made accessible through a web dashboard, a mobile app (iOS and Android), and a dedicated TV application. AQI.IN is not a third-party platform — it is fully owned and managed by Prana Air, ensuring seamless integration, faster support, and complete end-to-end air quality monitoring solutions.

Prana Air provides three access modes through the AQI.IN platform — all available out of the box with zero extra setup required. Web Dashboard (dash.aqi.in): Access real-time and historical data, download reports, compare parameters across multiple monitor locations, view pollution maps, and receive health advisories. Mobile App (iOS and Android): Available on the App Store and Google Play, the AQI.IN mobile app lets you monitor air quality on the go, set threshold-based alerts, view maps, and receive personalized health guidance. TV Application: The AQI.IN TV app displays live air quality data on Smart TV or Android TV screens — ideal for control rooms, corporate lobbies, and construction site safety boards.

Yes. Prana Air offers an LED display and Android TV dashboard solution specifically for construction sites. Live air quality data — including AQI, PM2.5, PM10, temperature, and humidity — can be displayed continuously on large LED boards or Android TV screens at the site entrance, safety office, or worker rest areas. This real-time visibility helps workers and safety officers take immediate protective action when pollutant levels cross safe thresholds, and it demonstrates regulatory compliance visibly to on-site inspectors. The TV dashboard is controlled and managed through the AQI.IN mobile app.

Yes. Prana Air's ambient monitors are used at construction sites in compliance with Delhi Pollution Control Committee (DPCC) and Brihanmumbai Municipal Corporation (BMC) guidelines. Both regulatory bodies mandate real-time air quality monitoring at large construction sites to curb dust and particulate pollution. Prana Air's monitors fulfill the requirement for continuous PM2.5 and PM10 data logging with cloud-based accessibility, allowing site managers and compliance officers to submit data reports to the authorities. The CAAQMS model is configured to meet the technical specifications outlined by CPCB and state PCBs for ambient air quality monitoring networks.

As per CAQM guidelines, all construction and demolition projects with a site area of 500 square meters or more in Delhi NCR are required to register on the government's online portal and install accurate PM10 and PM2.5 sensors linked for live access by CPCB and other government bodies. Prana Air's ambient monitors are compliant with mandates from regulatory bodies across multiple states and cities, including DPCC, UPPCB, RSPCB, and HSPCB covering Delhi, UP, Rajasthan, and Haryana, as well as BMC, TMC, and NMMC in the Mumbai region, AMC (Ahmedabad), and PMC (Pune).

Yes, and this is a key differentiator. Many ambient monitoring vendors build solutions primarily targeting the Delhi NCR market due to DPCC mandates. Prana Air has engineered a complete compliance solution that covers every major regulatory framework across India — DPCC, UPPCB, RSPCB, HSPCB, BMC, TMC, NMMC, AMC, PMC, and Himachal Pradesh state norms — under one product ecosystem. This means a construction company or real estate developer operating projects across different states can use a single Prana Air solution for all sites — with the same device, the same AQI.IN dashboard, and the same API data pipeline — without sourcing different equipment for different regulatory jurisdictions.

Yes. Under GRAP — the emergency dust control framework enforced in the National Capital Region — construction sites above a certain area threshold are legally required to install continuous ambient air quality monitors for PM10 and PM2.5 and keep data accessible to authorities. Prana Air's ambient monitors support this through real-time cloud data logging, GSM-based transmission for sites without stable internet, tamper-evident micro SD-card data logging as a backup, and report generation via the AQI.IN dashboard. Site managers can share direct data access links with DPCC or other inspection authorities, simplifying GRAP compliance significantly.

Yes. Prana Air provides a dedicated API data service that transmits real-time and historical air quality data from the monitor directly to any government-authorized web portal. The API service is designed for 100% uptime with reliable, stable, and secure data transfer — fulfilling the requirement that CPCB, DPCC, and other bodies can access data at any time without manual reporting by the site operator.
