PAQS air data APIs use a combination of URL paths and payloads for security reasons.  APIs use HTTP basic authentication wherever specified.  The payload format is JSON.  All methods will be standard HTTP methods like GET, PUT, POST.

As the REST API is based on open standards, any web development language can be used for accessing the API.  All API accesses will be over HTTPS. All APIs use a URL-based version scheme.

API is called at a frequency of 5 minutes Environmental Sensors for parameters and 1 hour for AQI in a year.


The pollution data is sensed and stored in the PAQS cloud and from our cloud, we push the data through WebSockets to the end server.

Widget / Web App

Widget API indicates current pollution levels in various locations. Widget for Screenshot of AQI

Mobile App

Environmental data can be easily accessible through mobile apps and it is easy and user friendly.

Lead pollutants

Criteria pollutants such as PM10, PM2.5, SO2, NO2, CO, and O3 and other additional parameters like lead and ammonia are included for calculating air quality index(AQI)


To provide real-time alerts for various pollutants crossing the breakpoints, alerts for outages, alerts for the health status of the device, alerts for noise level reaching breakpoints, alerts for AQI levels.

Emergency Intervention

Immediate actions to be taken during floods or other natural disasters to minimize the harm from the real-time data alerts provided by the devices.
