AWAIR

In Africa, the absence of an extensive meteorological device network has posed a significant challenge for environmental research, hindering accurate ground-truth data acquisition. This limitation affects various sectors, including government initiatives, urban planning, pollution control, etc.

Recognizing this gap, Awair emerges as a groundbreaking solution, offering an advanced, cloud-connected, real-time platform for environmental data. Awair aims to empower top universities, research labs, government agencies, and African industrial applications by providing accurate meteorological insights, facilitating informed decision-making, and sustainable solutions for environmental challenges.

Awair's data awareness, research, and analytics capabilities present a transformative approach to addressing the pressing issues related to the environment in the African context.
