| Microcontrollers (MCUs) | Low-power computing devices for IoT applications | Sensing and monitoring of production line equipment, motor control |
| System-on-Chip (SoC) | Integrated circuits that combine multiple components on a single chip | High-performance computing, advanced sensor integration |
| Industrial-grade sensors | Specialized sensors designed for industrial environments | Temperature, pressure, vibration sensing |
The choice of hardware depends on the specific use case and requirements. For example, microcontrollers are suitable for simple sensing and monitoring applications, while system-on-chip devices offer more advanced capabilities.
3. Cost Analysis
| Cost Component | Estimated Cost (JPY) |
|---|---|
| Sensor costs | ¥5,000 – ¥50,000 per device |
| MCU/SoC costs | ¥10,000 – ¥100,000 per unit |
| Networking infrastructure costs | ¥500,000 – ¥5,000,000 per installation |
The cost of IoT devices and infrastructure can vary widely depending on the specific requirements and scale of deployment. However, in general, the upfront investment is offset by the long-term benefits of increased efficiency and reduced maintenance costs.
4. Security Analysis
| Security Threat | Description | Mitigation Strategies |
|---|---|---|
