RESPIRERManage supplier listing

Continuous ambient and indoor environmental monitoring archive from a deployed internet-of-things sensor estate of roughly 2,500 devices across 25+ Indian cities plus international clients in Sweden, the United Kingdom, Oman, South Africa, Pakistan and Sri Lanka. Measured parameters span particulate matter, nitrogen dioxide, carbon monoxide, sulphur dioxide, ozone, carbon dioxide, methane, oxygen concentration, noise levels and weather, transmitted over narrowband cellular links and delivered through a cloud analytics platform with alerting. Distinctive licensing value: devices are scientifically validated against Federal Equivalent Method grade reference equipment, a rarity among low-cost networks, and the estate includes rural deployments under a national rural monitoring programme built with a leading Indian institute, a segment almost entirely absent from commercial air-quality datasets.
