The University of Birmingham led an environmental project called HiTemp, which deployed 250 ambient temperature sensing devices and 30 automatic weather stations in the city of Birmingham. They access the Internet wirelessly or by wire to enable data connectivity. Researchers say this is the world's densest environmental monitoring network for studying urban heat island effects.
Researcher Eliot Warren of the project said in an interview with Xinhua News Agency that the data collected by these devices can be transmitted back to the university's servers for analysis and shared with relevant departments in real time through wireless and wired networks.
He said that the project uses the recently developed IoT technology (that is, the various objects connected by the Internet) to collect data through a number of scattered, simple-structured but interconnected sensors, enabling low-cost deployment. It has greatly improved the efficiency of equipment use and effectively reduced the cost of the entire project implementation."
Warren believes that these technologies can be applied to a wider range of environmental monitoring projects in the future, including monitoring air pollution, carbon dioxide emissions, etc., to provide more targeted reference data for green city planning.
Not only scientific research, but also the lives of ordinary people can benefit. For example, the research team at the University of Hertfordshire in the United Kingdom has proposed a smart home solution that integrates Internet of Things technology.
According to John Sio, a researcher at the school, this solution is mainly implemented by deploying multiple sensors with wireless network connection at home. Air conditioners, refrigerators and other appliances can be connected to the cloud server, and users can use mobile devices such as smart phones. It can be monitored and controlled at any time, and it can be seen at a glance at home conditions to avoid potential safety hazards and unnecessary energy consumption.
Another environmental protection of this kind of smart home is that energy-consuming equipment such as air conditioners will gradually learn the daily usage habits of users, automatically adjust the indoor temperature, and save energy. In addition, since the devices in the home are all connected to the network, the maintenance status can be transmitted to the manufacturer in a timely manner under the authorization of the user, reminding them to maintain in time without the user having to worry about.
The British government is also vigorously promoting a smart meter project costing more than 10 billion pounds, which is the UK government's largest investment in the Internet of Things. The project plans to allow every household in the UK to use smart meters that can access the Internet by 2020, and monitor the energy usage of each household in real time. Up to now, 1.6 million smart meters have been installed, and eventually 26 million may be installed.
This smart meter is directly connected to the power and gas company's servers, and will be able to push prices and other information directly to the user's smartphone, reminding them when the price of electricity will rise or fall, allowing users to use electricity more selectively. Open electricity peaks.
On the supply side, smart meters can help energy providers optimize energy allocation. For example, when using electricity, when using traditional instruments, since it is impossible to accurately measure the electricity consumption of each household in real time, the power supply company can only allocate extra power to each household according to the estimation to ensure that they obtain stable power supply, which will cause waste. After using the smart meter, each household's power consumption information will be transmitted to the power supply company for analysis in real time, and the computer system can distribute power to each household more accurately according to the need to avoid wasting energy.
British Prime Minister David Cameron mentioned in a report published last year that the Internet of Things can help reduce energy consumption and make home life more convenient. This technology "will bring about major changes in our lives." To further popularize relevant technologies, the UK government is planning to build more network infrastructure, including opening more wireless spectrum.
