| Abstract: | The zero-cross modulation technology uses exsisting power distribution network as transmition carrier. Because it needn't increase additional system equipments, it is low-cost. In this paper, the design of alarming system of temperature and humidity based on zero-cross modulation technology and the constitution were introduced. By field application, it made chear that the design is in reason and the reliability is high. |
