Hi friend.
The MA5600T/MA5603T/MA5608T provides an environment monitor serial port used for connecting the serial port on a monitored device. By running the master-slave node protocol or access network protocol between the two serial ports, you can monitor the environment of the device directly or from a remote end. The environment parameters such as temperature, humidity, and power voltage can be monitored to ensure that the MA5600T/MA5603T/MA5608T can work properly in a suitable environment
