Parameters of IOT Cellular Modem

Working Mode of IOT Cellular Modem

1.HTTP Client
Support serial data transmission to designated server via HTTP.
2. TCP Client
The serial server actively initiates a TCP connection to the server. If it fails, it will continue to reconnect until it succeeds. If the connection is successful, the server and the serial device can perform two-way transparent data transmission.

• Application
• of
• IOT Cellular Modem
• ZHC4941 can be applied to the urban road water monitoring system, which can monitor the water level of various low-lying road sections in the urban area in real time and realize automatic warning. With the help of this system, the municipal management department can grasp the waterlogging situation of the whole city as a whole and carry out drainage dispatch in time. The traffic management department can obtain the real-time stagnant water level of each road section through this system, and use radio, television and other media to provide travel guides for the general public to prevent people and vehicles from entering the deep water section and causing serious losses.

Founded in 2015, Chengdu Zongheng Intelligence Control Technology Co., Ltd. is a high-tech enterprise focusing on the research, development, production and sales of Internet of Things communication control terminal products and related overall solutions. Takes the IOT intelligent communication terminal as the entry point, combines edge computing and big data cloud platform, and realizes data collection, transmission and intelligent control and other functions in the application of the Internet of Things. At present, the company's products have been widely used in intelligent water conservancy, intelligent agriculture, intelligent audio-visual and other scenes.
