a) Air quality egg

Egg is a WiFi-enabled device that uses sensors to record changes in the level of specified air pollutants. Each egg can detect at least one air pollutant, including NO₂, CO₂, CO, O₃, SO₂, particulates and volatile organic compounds (VOC). It can track all changes and automatically upload the data to the cloud, which can then be accessed through our web portal, mobile app, or by connecting Egg to a computer for manual download.

b) TZOA

TZOA can not only monitor the impact of the environment on users, but also show how people affect the environment, and generate a street-level pollution map in the user community. TZOA is like a badge that can be attached to clothes, shoes, and bags. This optical particle counter will collect the city's air environment quality data for you and visualize it on the supporting app. At the same time, TZOA will mark real-time contaminated areas and uncontaminated areas, and users can choose destinations and routes for outdoor sports such as walking based on this information. When the pollution level of the local environment increases and the air quality is low, TZOA will issue a warning and advise the user to change the place. TZOA can also monitor indoor data to help control the air quality at home.

c) Flow

A portable and intelligently tracking air quality device designed in cooperation with the Frog sensor. This device is about the size of a flip phone, and has a belt that can be easily connected to your backpack. It has timely monitoring of particulate matter (including the most dangerous particulate matter PM2.5), nitrogen oxide, and ozone in the area around the user. , Volatile organic compounds, temperature and relative humidity sensors. People can view the pollution levels monitored by Flow through a mobile app. The user presses the activation light button on the device. If it glows white, it means that the air is clean. The light will gradually turn red as the air pollution worsens. The health level is based on the recommendations of the World Health Organization (WHO). In addition, the LED lights are arranged like the clock face and can display other features, each representing the average air quality that the user has breathed in the past hour. Users can get their pollution intake within 12 hours at a glance.

The data collected by the personal Flow device helps Plume draw what it calls a "real-time air quality map", which can be used to display the pollution level at a given moment through the Flow app.
