　　Use this reference design to quickly establish awireless network that connects various types ofsensors for condition monitoring directly to the Cloud.Condition Monitoring is based on a regular orpermanent recording of the machine condition which isnecessary for predictive maintenance. Inputs such asRS-232, RS-485, IO-Link or resistance temperaturedetectors (RTDs) are included in the design to monitor different sensors and machines.

　　Condition monitoring is used to monitor the condition of machines and systems in a wide variety ofapplication areas. Compared to the frequently used preventive maintenance, Condition Monitoring is amore efficient and safe alternative. Preventive maintenance means that parts of the engine, such asbearings or shafts, are replaced too early due to fixed maintenance intervals on machines. As a result,terms are shortened unnecessarily, capital is given away. Likewise, this method is not able to detect andaccurately locate defective components before failure. Defective components can cause considerable damage and downtime during machine operation. With condition monitoring or condition-basedmaintenance, both can be realized. Component faults are detected early, and residual storage lives aremaximized. This way costly downtime can be avoided, as well as cost savings through full utilization of theruntimes of critical machine components.

　　Thanks to intelligent sensor technology, condition-relevantmachine parameters such as machine vibrations, vibrations or temperatures are recorded directly at thesystem during condition monitoring. Using mathematical analysis methods and corresponding software, these parameters can be permanently analyzed. The general machine status as well as individualcomponents can be monitored almost in real time online. The sensors used for the data collection areoften housed in hard-to-access locations, and the sensors may not be accessible through ordinary wiredconnections. As the sensors usually must communicate with upstream data-gathering nodes, wirelesscommunication is required. With the onboard, multistandard 2.4-GHz wireless CC2652 MCU and theCC3220 Wi-Fi MCU, this reference design can support different wireless protocols like Thread, Zigbee®,Bluetooth® low energy (BLE), Wi-Fi® or proprietary solutions.
