Xensor, a business that previously developed and manufactured IoT sensor hardware, tackled the challenge to provide the IoT infrastructure required to construct smart cities. Xensor project has improved the efficiency of data storage and transactions by automating specific aspects of data management, thus lowering the cost of constructing IoT communication
networks. Xensor has also integrated blockchain technology in device networks to ensure the credibility of the data, and plans to implement an incentive policy to its hardware clients.
Blockchain technology is ideal in supporting data transmission, automated services, monitoring, and mutual sharing services among devices within IoT networks. Although some drawbacks hamper the processing time and scalability of blockchain technology, the shortcomings can be compensated by utilizing IoT-specific main-nets and exploring everdeveloping innovations.
Xensor will develop its project in the following order: asset surveillance, asset control, communication networks, and data market. Since Xensor has developed and commercialized sensor devices, the two stages of asset surveillance and asset control are already obtaining good results. Currently, Xensor is in the process of creating scalable IoT communication networks that can easily be adapted in various fields.
Asset Surveillance – Monitoring Farmland, Factory, and Buildings
Traditionally, various equipment were necessary to safely monitor a building 24 hours a day, requiring many maintenance personnel to make rounds of inspection and tend the equipment. However, hiring a considerable number of employees for every building is inefficient
in terms of both time and cost. Such a feat can easily be replaceable by automated sensors.
A large building with total floor area of 26,000㎡ requires approximately 200 sensors. Connecting all these sensors with wired cables is both physically and financially cumbersome, and even with conventional wireless sensors, the fee per circuit is still costly due the shortcomings of IoTs.
Xensor provides the solution by applying low power wide area (LPWA) technology to connect sensors that are as far as 15km from the gateway. Even with a vast number of walls, a building with total floor areas of 26,000㎡ and 66,000㎡ requires only one and three gateway(s), respectively, to construct communication networks that span the entire area. With Xensor, only about five maintenance personnel is required to cover a total floor area of 26,000㎡.
Asset Control – Automation of Farmland and Factory Facilities
Farms that are immense in size, as those in California, require helicopters to spread agricultural pesticides. In order to reduce the inefficiency that results from using expensive helicopters, a novel method of watering the crops by installing equipment in sectors of the farmland was developed. Unfortunately, the innovation could not distinguish areas that were well
watered from those that were dry, and the produce worsened.
Such a problem can be easily solved by using sensors that monitor the humidity of the land and IoT technology that controls water from the sprinklers. However, it would be very inefficient to use conventional IoT technology such as Wifi and Bluetooth to cover the vast area of farmland.
Xensor provides the solution with its miniaturized gateways that can connect sensors within a 15km radius. Xensor’s products can thus create automated “smart farms,” and even smart factories using the same technology in appropriate positions.
Just dozens to hundreds of Xensor gateways, which act as the backbone of the infrastructure of smart cities, can establish IoT communication networks throughout an entire city at a low cost. Currently, Xensor provides asset surveillance and control services with its sensors
and communication technology. By advancing into the third stage, the communication network, Xensor will be able to provide more diverse services using the scalability of IoT devices and networks.
Many countries in South-East Asia, which are home to some of the most famous tourist spots, are vulnerable to calamities and safety accidents due to the lack of city infrastructure. For instance, drainage systems become easily overburdened during rainy season, compromising roads and thus tourist services. IoT solutions may provide a solution to this predicament, but the substantial cost deters the city from installing the necessary equipment.
Xensor, however, can be an option for these cities in developing countries of South-East Asia, as it can set up communication networks at a lower installation cost and an even lower maintenance fee.
Xensor sensors can currently detect fire, leaks, power failures, and malfunction, and a new sensors with functions detecting air quality and floating population are under development. The aggregated data from these sensors may contain danger-related information of a particular
area, providing valuable information with monetary value.
For example, black boxes in automobiles are usually used to assess car accidents, but car insurance companies provide discounts if the car owner chooses to install a black box in his or her car. Similarly, Xensor can provide data that predicts danger and accelerates emergency response, which may also lead to financial incentives after the installment of Xensor devices.
Xensor gateways can be applied in all services of a smart city once it is installed. In particular, if autonomous cars are commercialized, Xensor can be used to calculate the risk of car accidents and predict traffic. Xensor can collect data from any location, and it is not limited to buildings, farmlands, and factories. Such data can be of fiscal value to insurance companies,
investment banks, governmental institutions, consulting firms, and credit card companies.
How to buy Xensor (XSR) in 2020?
If you want to buy cryptocurrencies like Bitcoin (BTC), Xensor (XSR) or any other altcoins, you have two options: if you don’t mind KYC (Know Your Customer) policy, you can create an account with CoinBase. Because of KYC policy, the site will ask for various papers like ID, proof of address and so on. If you want to go anonymous, you can create an account with Binance or KuCoin. On those last two sites you won’t need any proof of identity as long as you don’t exchange large amount of cryptocurrencies. Just click on one of the above link and follow some simple steps to open your own crypto account.
