Components of the system.
| Hardware components | Description | |
|---|---|---|
| Processor | nRF5340 Development Kit | It is the brain behind the system. It is an SoC, powered with two-arm® cortex®-M33 processors, has all the processing power to execute machine learning model and built-in communication modules such as BLE, Zigbee, Thread. The kit is used to design sensor nodes. |
| Raspberry Pi 4 | It has Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5 GHz. This kit is used to design gateway nodes for the system. | |
| Sensors | X-NUCLEO-IKS02A1 Shield | It is an industrial motion MEMS sensor expansion board. It embeds the following modules. |
| (i) ISM330DHCX 3-axis accelerometer | ||
| (ii) 3-axis gyroscope | ||
| (iii) IIS2MDC 3-axis magnetometer | ||
