HT-8A eight-channel alarm control host
How data is displayed in real time on the Internet
The alarm control host is used in conjunction with the alarm detector, in addition to receiving the signal of the gas detection detector, and when the measured value reaches the set alarm value, the control host emits sound and light alarms, and at the same time outputs the control signal (switching contact output), prompting the operator to take safety treatment measures in time, or automatically starting the pre-connected control equipment.
It's okayOn this basisWith our companydevelopmentofData center software and WEBinterfacesoftware, using GPRS/3G DTU to upload meter data to the central server, so as to realize real-time display of meter data on the Internet.MaxFeatures:Data Internet display in real time,Mobile App alarm and real-time viewing,It can be connected to a variety of sensors or transmitters such as temperature, humidity, and pressure。
Featured extensions
l Internet real-time display, no need for complicated settings, plug and play;
l Mobile APP alarm monitoring and display;
l Connect to the computer to set all parameters with one click, monitor and store the computer in real time, and support secondary development.
