  • Introduction​ of MQTT Modem

 

ZHC492C support 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) Output, 4 channel analog quantity (current 4~20mA) detection, 1 channel RS485 transparent network IO products, compatible with Modbus RTU/TCP protocol. With remote control as the core function, it is highly easy to use, users can easily and quickly integrate into their own systems to realize remote and local control based on LTE, RS485.

 

 

  • Function​ of MQTT Modem

 

Client can send Modbus commands to ZHC492C through the network and serial port to read and write DO status.
DO of ZHC492C support active reporting, restarting the holding relay status, output holding time, timing flip.

 

ZHC492C can realize long-distance data transmission of one to one, one to many and many to many.

Customers do not need to develop the server, but configure the cloud networking function of the device.

 

Application of MQTT Modem


1. Automatic rainfall monitoring
Enhance meteorological service capabilities, meteorological service levels, and achieve the role of disaster prevention and reduction. Automatic rainfall collection is an automatic observation instrument used to collect ground rainfall information. It can accurately record the precipitation per minute. The automatic rainfall monitoring station is an unmanned automatic rainfall recording instrument, which can be used as an unmanned portable self-recording station.


2. Automatic water level monitoring
Grasp the dynamics of the water level, provide accurate basis for the adjustment of the water level of rivers and lakes, and effectively control the over-exploitation of groundwater, conserve groundwater sources, improve the ecological environment, and delay and prevent geological disasters.
