Case 1: Real-time medical monitoring
Wireless sensor networks based on the Internet of Things technology can play an excellent role in detecting human physiological data, the health status of the elderly, hospital drug management, and telemedicine. By placing sensors for temperature collection, breathing, blood pressure and other measurement on the patient, the doctor can remotely understand the patient’s condition. The use of sensor networks to collect human physiological data for a long time is very useful in the process of developing new drugs. With a little productization, this system can become a safety assistant for the elderly and patients with mobility impairments. At the same time, the system can also be applied to the rehabilitation centers of some disabled persons to accurately measure the patient’s various limb recovery progress, thereby providing a valuable reference for the design of rehabilitation programs.
Case 2: Released fish has an “identity card”
Don’t be surprised if you happen to see a yellow label on the back of silver carp and bighead carp resembling a small antenna on the back of Li Lake in Wuxi. The Wuxi Municipal Agriculture Committee released 300,000 small fish in Lihu this year. Unlike previous years, 3,500 silver carp and bighead carp that had been grown for about one year were implanted with high-tech chips, which became an effective carrier for detecting the release effect.
The chip is used to record the initial information of the fish release time, release location, and fish physical condition at the time of release. Researchers scan the chip with a computer to find the initial data to study the living conditions of fish in Lihu Lake, the impact of environmental changes on the fish, etc. They can also calculate the cyanobacteria eaten by the changes in fish body weight, and finely measure the caladium. Improvement of the ecological environment of the lake.
Case Three: Internet of Things Refrigerator
When you come home from work for a day, you want to make a lotus seed and longan soup. When you go to the refrigerator and check the display on the outside of the refrigerator, you find that there are red dates and lotus seeds in the refrigerator, but no longans. It doesn’t matter, this refrigerator has been connected to the world through the Internet of Things technology, immediately visit the Wal-Mart website, there are many dried longans to buy… This is the new life that the Internet of Things refrigerator brings to people.
The Internet of Things refrigerator can not only store food, but also realize the “dialogue” between the refrigerator and the food in the refrigerator. Refrigerators can obtain information such as the quantity, shelf life, food characteristics, and origin of the food they store, and feed the information back to consumers in a timely manner. It can also be connected to a supermarket, allowing you to know the product information on the supermarket shelves without leaving the house; it can formulate a reasonable meal plan according to the owner’s habits of taking and putting food in the refrigerator. In addition, it is an independent entertainment center, with network video phone function, can browse information and play videos.
