91% of people breathe polluted air
According to the World Health Organisation (WHO), 91% of the world population in 2016 was living in places beneath WHO air quality guidelines levels.
Air pollution poses a major health risk, while people are unaware of to what extent the air they breathe is bad. The limited number of costly measuring stations does not allow for a thorough examination of air pollution.
What is Nebo
Small, smart devices that sit outside your window and detect air quality by networking together to be as efficient as possible. Every time someone connects this device to their wifi - it extends the global air monitoring network.
Unlike reference sensors, the new digital sensors are smaller, more compact, much cheaper, easier to use and provide high-resolution spatiotemporal concentrations of air pollutants. They pick up odorless, invisible particles that are very harmful to our bodies.
Every major city contains hundreds of harmful substances that we breathe.
But in order to detect air pollution and warn you about it in time, you only need to identify one substance contained in almost all urban emissions - PM2.5
The mass concentration of PM2.5 is a key parameter for assessing air quality and its threat to human health. According to World Health Organization (WHO) standards, the average annual level of PM2.5 should not exceed 10 ug/m3 and the average daily level should not exceed 25 ug/m3.

Particulates are the most harmful form of air pollution because they can penetrate deep into the lungs, blood streams and brain, causing many health problems.

We were able to create a PM2.5 airborne fine particle detector that is as affordable as possible, high quality data, and incredibly easy to use.
Using a low-cost, high-precision Nebo sensor allows you to not only know the condition of the air in your area, but also to join a network that identifies the location and traces of pollution in real time. The more of these devices you have, the more data you can make predictions and advanced analytics, as well as alerting the public to air pollution.

So you become an environmental activist who helps fight climate change and global warming.

The Nebo sensor automatically detects and transmits air pollution, outdoor temperature, humidity and atmospheric pressure through your home wifi network. With a bright LED screen you get the data right outside your window, it's fully controllable from your smartphone and sends notifications so you can plan your walks or exercise.

How it works
This sensor works on the principle of laser scattering. The sensor has a fan which creates a controlled airflow so the environmental particulates pass through a focused laser beam.

The particulates cause light scattering which is detected by a photodiode and then converted into PM concentration with the help of its microprocessor.

For northern regions, an incoming air heater is installed, which ensures stable operation of the sensor, even at outdoor temperatures of -40°C .
The sensor has an environmentally protective housing and is fully prepared for outdoor use in all weather conditions.
The device has a 16x24 pixel color LED screen. The size and brightness of the pixels are chosen so that it is easier to read information through the window.
The device is attached to the window glass by a special magnetic system, it does not require additional installation. The diameter of the wire was chosen so as to fit into the joint between the window seals and not to bend.
The device connects to your home Wifi network and transmits data via API protocol to a unified system. All data is displayed on the Nebo platform through the website and applications.
The device is set up through the free app without any special skills.
