STMicroelectronics support condition monitoring and predictive maintenance industrial IoT designs with SensorTile wireless development platform, evaluation board and samples available from Anglia


The STWIN SensorTile wireless industrial node (STEVAL-STWINKT1) from STMicroelectronics is a development kit and reference design that simplifies prototyping and testing of advanced industrial IoT applications such as condition monitoring and predictive maintenance.

Condition Monitoring

Condition Monitoring (CM) is the monitoring of various parameters such as vibration or temperature to identify potential failures. This method aims at highlighting problems, allowing Preventive Maintenance to be scheduled before any damage occurs. Continuous condition monitoring techniques are normally used on equipment such as compressors, pumps, and motors.

Predictive Maintenance

Predictive Maintenance (PdM) is based on Condition Monitoring, abnormality detection and classification algorithms, and integrates predictive models which can identify the remaining machine runtime left, according to detected abnormalities. This approach uses a wide range of tools, such as statistical analysis and Machine Learning to monitor the state of the equipment.

Both of these techniques rely on accurate and detailed data collection which for Industry 4.0 is now an essential part of the monitoring process and helps ensure factory floor machines run smoothly and efficiently. A typical system will comprise of many combined elements which include sensors, data processing and data analytics.

Wireless Development Platform

To assist designers developing CM & PdM applications, STMicroelectronics have introduced the STWIN SensorTile wireless industrial node (STEVAL-STWINKT1) development kit which features a core system board with a range of embedded industrial-grade sensors and an ultra-low-power microcontroller for vibration analysis of 9-DoF motion sensing data across a wide range of vibration frequencies, including very high frequency audio and ultrasound spectra, and high precision local temperature and environmental monitoring. The development kit is complemented with a rich set of software packages and optimized firmware libraries, as well as a cloud dashboard application, all provided to help speed up design cycles for end-to-end solutions.

The kit supports Bluetooth Low Energy (BLE) wireless connectivity through an on-board module, Wi-Fi connectivity can also be added through an optional plugin expansion board (STEVAL-STWINWFV1). For applications which require wired connectivity this is also supported via an on-board RS485 transceiver. The core system board also includes an STMod+ connector which allows its capabilities to be further expanded using compatible, low cost, small form factor daughter boards associated with the STM32 family, such as the LTE Cell pack. The kit is provided complete with a 480 mAh Li-Po battery, an STLINK-V3MINI debugger and a plastic enclosure.
