The STEVAL-PROTEUS1 is an evaluation tool designed for temperature and vibration monitoring. It is based on a 2.4 GHz multiprotocol wireless SoC to address machine or facility condition monitoring for industrial applications.
The evaluation board simplifies the prototyping, evaluation and development of wireless industrial sensor nodes to enable the predictive maintenance. It comes with a LiPo battery and a plastic case. All components are mounted exclusively on the top side of the PCB to ensure an easy mounting on other equipment. The included comprehensive software and the firmware libraries with time and frequency domain vibration analysis ease your software customization and can reliably improve your time-to-market.
The main board includes the STM32WB5MMG ultra-low-power and small form factor wireless radio module. This module is FCC and IC certified (FCC ID: YCP-STM32WB5M001 and IC: 8976A-STM32WB5M01). It is based on the STM32WB55VGY wireless SoC, compliant with the Bluetooth® Low Energy SIG specification v5.2, ZigBee 3.0, and IEEE 802.15.4-2011.
The powerful Arm®-based Cortex-M4 with FPU and large memory allows running the embedded algorithm at node level.
The multiprotocol support ensures the development of applications with different types of connectivity, using a unique hardware. Moreover, the main board integrates the STSAFE-A110 secure element that provides authentication and secure data management services to a local or remote host.
The IIS3DWB high bandwidth (up to 6 kHz) accelerometer, the IIS2DLPC ultra-low power, and the ISM330DHCX inertial module (accelerometer and gyroscope) with MLC make the hardware ideal for a customized vibration monitoring development.
The STTS22H high accuracy temperature sensor has been integrated in the board, far from the heat noise sources (the power management and the microcontroller) to provide a more precise temperature measurement. Its exposed pad sensor feature allows the temperature sensor to be in contact with the surface target equipment.
An on-board external memory is connected via QSPI to the STM32WB5MMG module for data buffering and event storage.
The STEVAL-PROTEUS is LiPo rechargeable battery-powered. It can also be powered via USB (5 V at 500 mA) or via a primary battery (which is not included in the kit).
The power management features the ST1PS02 400 mA step down converter for low-power applications and the STBC02 for battery charging.
An application example firmware with dedicated algorithms is preloaded in the STM32WB5MMG flash memory for easy demonstration of wireless vibration and temperature node monitoring.
