The better way to
breathe in India.
A fully automated respiratory defense platform for individuals tracking exposure, schools taking precautions, and developers building clean-air intelligence.
Lodhi Road Atmospheric Station
How VayuDrishti protects you.
Three synchronized steps turning atmospheric telemetry into biological immunity.
Connect your sensor stream
We cross-reference 1,000+ CPCB, satellite, and community sensors so you never breathe blind.
Set your exposure limits
Block off hazardous morning inversion hours and automate safe outdoor limits for children.
Choose how to defend
Whether N95 respirators, HEPA air purifiers, or shifting school athletic meets indoors.
See how the day shifts.
Inspect real-time boundary layer dynamics across Delhi NCR with the diurnal timeline below.
Maximum vertical thermal convection mixing layer; lowest daily microgram particulate density.
Don't guess.
Know what you inhale.
The first environmental companion that translates microscopic aerosol physics into everyday clinical protocols for your family.
Test your clinical lung capacity using just your microphone.
In hospitals, Spirometry tests cost ₹2,000+ and require a ₹50,000 lab sensor. SpiroVision uses acoustic turbulence analysis right in your browser to compute Forced Expiratory Volume (FEV1), vital capacity (FVC), and detect acute smog bronchospasms in 10 seconds.

Clinical Lung Capacity in 10 Seconds
Hold your phone or laptop about 10 cm from your lips. Inhale deeply, then blast all the air out as hard and fast as you can into the microphone.
Expand lungs to 100% vital capacity.
Explosive exhalation into mic for 5s.
Acoustic AI maps Flow-Volume loop.
Your biometrics drive your particulate dose.
Standard apps assume you breathe the same sitting in a car as you do jogging. VayuDrishti connects directly to your smartwatch (Apple Watch, WearOS) or your smartphone sensors (live accelerometer step cadence & camera pulse PPG), correlating physical exertion with respiratory minute volume ($V_E$) to compute your true alveolar particulate dose.

Navigate by clean air, not just speed.
Google Maps routes you down congested arterial ring roads with extreme diesel soot. BreatheClean redirects commuters through natural tree canopies and green corridors—saving your cardiovascular health by trading just 3 extra minutes of travel.
BreatheClean™ Route Intelligence
Clean CorridorLow-Particulate Canopy Navigation vs. Diesel Arterial Highway
Canopy Greenbelt & Barakhamba Greenway
Follows Nehru Park & diplomat buffer zones where mature foliage filters up to 68% of street-level PM2.5.
Ring Road & Janpath Arterial
Passes through high-exhaust roundabouts and traffic choke points with stagnant boundary layer.
Avoid toxic exposure overload
Only get exposed when atmospheric dispersion is high. Set daily exposure caps and add buffers around morning inversion hours to protect your lungs.
Stand out with a verified clean-air link
Customize your campus or clinic link so it's short and easy to remember for parents. Clean, verified, unforgeable.
Automated real-time CPCB sensor stream & classroom HEPA filtration status for 2,400 students. Safe air verified daily at 05:45 AM.
Streamline your campus directives
Let faculty overlay live particulate curves, receive automated morning directives via text, and reschedule outdoor sports with ease.
Reduce health emergencies with automated alerts
Easily send SMS or push alerts about particulate spikes, and send automated directives to gather relevant exposure information before morning bells.
...and so much more!
Engineered with production-grade telemetry, sub-second latency, and clinical respiratory precision.
BreatheClean™ Route Engine
Reroutes daily commute through green corridors, cutting toxic PM2.5 load by up to 71%.
Smartwatch Bluetooth GATT
Pairs live with Apple Watch and WearOS devices via W3C Web Bluetooth (0x180D).
Phone Motion Pedometer
Uses device accelerometer to measure live step cadence and calculate physical minute volume.
Phone Camera Pulse (PPG)
Optical capillary blood flow measurement using your phone camera flash—zero watch required.
Real-time CPCB Telemetry
1,024 national ground stations ingested every 60s with boundary layer validation.
Diurnal Inversion Physics
Solar boundary layer mixing algorithms calculating optimal daily outdoor windows.
School Sentinel Mode
Zero-friction morning assembly and outdoor recess safety verdicts for campus principals.
Instant SMS via Amazon SNS
Sub-second emergency warnings triggered to parents when localized particulate spikes breach caps.
All your key telemetry in sync with your health
Direct connection with CPCB, SAFAR, NASA FIRMS, and AWS Cloud infrastructure. Reliable air intelligence everywhere your family works, learns, and breathes.
Frequently asked questions.
Standard government portals present historical 24-hour rolling averages as a single delayed aggregate index. VayuDrishti ingests raw micro-sensor streams every 60 seconds from over 1,024 CPCB stations, correlates them with boundary-layer thermal inversion physics, and converts raw numbers into immediate personal action protocols (e.g. safe outdoor hour windows and automated school assembly closures).
