Blockcraft is the world's first commercial Internet of Things sensor that uses a building block architecture, which can quickly develop the most suitable customized products according to application needs and installation fields. The Blockcraft sensor is also the Internet of Things product on the market that pays the most attention to the concept of sustainable development. The building block architecture allows for the reuse of communication and sensing modules, reducing the waste of electronic parts caused by repeated development and production. It can also connect to external solar energy and other power generation modules. With the low power consumption characteristics of the sensor, it can be easily used outdoors to achieve real power self-sufficiency. Currently, Blockcraft has been applied in fields such as disaster prevention monitoring, cold chain logistics, and smart cities.
