Can IOT sensors perceive words?

IoT sensors can't perceive words. The key technologies of the sensing layer of the Internet of Things include sensor technology, radio frequency identification technology, two-dimensional code technology, Bluetooth technology and zigbee technology. When the main function of the sensing layer of the Internet of Things is to collect and supplement the corresponding information, RFID technology will be used to identify the goods first, and then the highly integrated micro-sensor installed on the goods will sense the information of the goods and their environment and their own state, so as to realize real-time monitoring and automatic management of the goods, and this function can be realized.
