In most IoT application scenarios, the environment is very harsh. In the low-temperature environment in the north, the temperature can reach -10°C, or in some places, the summer temperature can reach 40-45°C. Ordinary electronic equipment will not be able to work in this environment, and some equipment will crash directly. Similarly, in some application scenarios such as water plants and factories, the ambient humidity is 3~4%. Ordinary electronic equipment cannot work properly in such an environment. Not only interference from the natural environment, but also other interference, such as electromagnetic interference, etc., will prevent ordinary electronic equipment from functioning properly.
In the Internet of Things, most DTU R&D and manufacturing manufacturers, in order to solve this problem, produce equipment with the above issues in mind. The equipment produced are all industrial-grade products, which are sufficient to face these problems. For example, the industrial-grade DTU produced by Chengdu Zongheng Intelligent Control undergoes high and low temperature tests and electromagnetic interference tests before being sold.
