Woman blowing nose because of spring pollen allergy

An application warns in real time about the amount of pollen in the city

Since the beginning of spring, the allergic season is in full swing. The number of people with allergies continues to rise (1), Lify Air solution provides greater comfort to patients. “Entrepreneur and allergy sufferer, I approached the CNRS lab in Orléans to develop innovative sensors that measure pollen in the air. Algorithms enable them to identify, count, and provide real-time and localized information on the air condition of thirty allergens, ”says Jérôme Richard, President and Co-Founder, Lify Air.

Network sensors

Compared to the reports available so far, it broadcasts alerts on a departmental basis and with a delay of at least a week. To ensure accurate information, Lify Air allows municipalities and intercoms to install sensors in their territory that allow their people to know the amount of pollen, anticipate their treatment, or change their travels.

“The sensors work on the network and we install them At least three in small towns and ten or fifteen depending on the area. The investment in each sensor is 200 3,200, of which ,000 4,000 is added to the subscription, ”says Jerome Richard.

Live Pollen is a start-up utility that allows all residents to benefit from updated data that is very close to where they are. The city of Istres (43,600 citizens, Bouches-du-Rhône), which enabled five sensors in early May, chose to integrate data into its new application, Istres and you. “The application provides a variety of announcements, events, jobs … therefore, measuring pollen risk. We provide connected services that meet the real need of the people. A link will allow you to download live pollen,” said Mayor Patrick Grimaldi.

Smart-City approach

For a municipality that has been involved in the Smart-City approach for ten years, the data from Life Air sensors can then be used. “Currently, all data from our other connected tools is uploaded to our dashboard. The second step is to work with medical professionals and data specialists to overcome them with weather and allergy peaks, ”continues Patrick Grimaldi. The evolution of nature and the levels of recorded pollen will lead the municipality to think about the species planted in its territory in order to avoid being highly allergic.

Pascal Vertanesian, Deputy Mayor of Vanuatu (27,800 people, Hauts-de-Seine), Responsibility for urban development, environment and heritage

“Since April, we have been testing three sensors installed a month ago in three municipal buildings covering our entire area. As a municipality in the first belt of Paris, we are concerned about air quality. We have two large parks with 2,500 species of trees.

Therefore, our people need information about pollen. As part of the communication that took place around the launch of this service, we interviewed an allergist from the city who welcomes access to this information. In the future, the collected data may feed our reflection on the establishment of new tree species. ⁇
