The problem of pollution is more serious in outer space, but it is also quite bad on Earth. Colorless and tasteless toxins and chemicals in indoor air are susceptible to illness. American allergy experts estimate that 50% of the disease is caused by indoor air pollution. What causes indoor air pollution? What are the symptoms? How to use IoT to reduce air pollution? How to use bionics to help? Should you continue reading? Monitor the air quality index of your place of residence and decide for yourself. Hazardous sources and symptoms According to the World Health Organization, more than 4 million people die from indoor air pollution each year. Many household products release harmful toxins, such as gas stoves, building materials and furniture made from certain pressed wood products, asbestos insulation, carpets, household cleaning products, central heating and cooling systems, and more. Air filters also do nothing because these contaminants are gaseous and freely pass through. The main sources and symptoms of contaminants include: â—† Trichlorethylene (paint, paint, varnish, paint remover) Symptoms: Short-term exposure can cause irritation, dizziness, headache, nausea and vomiting, and may then cause drowsiness and coma. â—† Formaldehyde (wax paper, particle board, plywood, synthetic fiber) Symptoms: Short-term exposure may irritate the nose, mouth and throat, causing serious throat and lung edema. â—† benzene (plastic, resin, detergent, paint) Symptoms: Short-term exposure may cause eye irritation, drowsiness, dizziness, headache, increased heart rate, headache, confusion, etc., which may result in loss of consciousness. â—† xylene (leather, tobacco smoke, rubber) Symptoms: Short-term exposure may irritate the mouth and throat, causing dizziness, headache, confusion, heart problems, liver and kidney damage, and coma. â—† Ammonia (window cleaner, floor wax) Symptoms: Symptoms related to short-term exposure include eye irritation, cough and sore throat. Indoor air pollution affects productivity MK Think company long-term commitment to intelligent space design, familiar with how indoor air pollution affect productivity. According to data from Harvard Public Health Center, Signo Uddenberg, head of innovation at MK Think, said: "Increasing carbon dioxide (CO2) by 400 ppm (one millionth) will reduce productivity by 21% and make people feel tired and in higher concentrations, The longer the exposure to carbon dioxide, the worse it will be; MK Think envisions deploying IoT sensors indoors to assess indoor environmental variables and analyze the data to reduce indoor pollution and improve the working environment. " Air quality sensor Foobot is a well-designed small air monitor with multiple sensors for continuous monitoring of indoor air quality. It integrates with other IoT temperature control products such as Nest and ecobee, and provides an open API for other applications to integrate. Use IoT technology to reduce indoor air pollution It monitors the parameters include: â—† Volatile organic compounds (VOCs), including formaldehyde, toluene and benzene. By using metal oxide semiconductor to detect and provide overall data level. â—† Carbon dioxide concentration is calculated using algorithms and VOCs are monitored by specific sensors. Particulate matter is detected by an optical sensing system that can detect even the smallest particles that breathe into the lungs. PocketLab Air is an all-in-one science lab that studies climate change and air pollution and measures carbon dioxide, ozone, particulate matter, temperature, humidity, pressure and light. The Blueair Aware Intelligent Air Detector monitors and controls indoor air quality and detects particulate matter, volatile organic compounds, carbon dioxide equivalent, temperature and humidity in the air through Wi-Fi 802.11B / G / N, 2.4 GHz Secure Open / WEP / WPA / WPA2 for communication. The Blueair Friend app is continuously updated and sends average data to Blueair Cloud every five minutes. Its application, Air View, displays air quality information in real time around the world using local IoT sensor data. Use IoT technology to reduce indoor air pollution Blueair Aware bionics NASA is researching how to keep the astronauts' living environment clean and discovering that bionic methods have a significant effect on reducing air pollution. This approach takes advantage of natural causes to solve complex human problems: "The roots of plants and their associated microbes destroy pathogenic viruses, bacteria and organic chemicals and eventually transform all air pollutants into new plant tissues." Foobot explains: "Many substances that are toxic to humans can be broken down by plants into harmless substances that are assimilated to form part of the plant tissue, and bacteria that live in the soil around the plant roots can also metabolize the harmful substances." Plant-based air purification methods have three benefits over air filters: 1, artificial filter to remove harmful compounds in the air, but can not provide oxygen. 2, the filter can absorb pollutants, but can not remove them, the filter must be regularly cleaned. plant
