1.1 Scope of Application
IEMS Simple Monitor V.300 is an intelligent monitoring and control product. It is generally applicable to intelligent display terminal products, video terminal products, industrial automation terminal products, such as advertising machines, digital signage, intelligent self-service terminals, intelligent retail terminals, O2O intelligent devices, industrial control hosts, robotic devices, etc.

1.2 Product Overview
The environmental monitor communicates with the remote server through the integrated WIFI module to provide real-time environmental monitoring information reporting, remote control, and online program upgrade. The board integrates temperature and humidity sensors, relay switches; external interfaces support fan PWM control, fan speed feedback collection, access control monitoring, flooding, smoke, light sensor, LCD brightness monitoring interface. The temperature can be detected by the onboard or external temperature sensor, match with the preset temperature value and automatically control the fan. A RS485 communication interface is reserved for communication with the terminal.
