Because the wireless sensor needs to detect data through the wireless communication protocol and send the data to the remote server, the wireless sensor using different communication protocols can only be used in specific application scenes, and the use range of the wireless sensor is limited. Meanwhile, in order to ensure the safety and the data accuracy in the data transmission process, corresponding wireless sensors are required to be selected according to application scenes, so that the hardware cost of the Internet of things system is increased and the Internet of things system is inconvenient to arrange.
