Analog Sensor Access & Data Processing
⏱️ Estimated Duration: 20 minsMaster the wiring, range conversion, and automation applications of analog sensors (current, voltage).
📚 Learning Points
- Analog Concept: What analog signals are and the difference from digital signals
- 4-20mA Current Signal Sensors: Wiring methods (two-wire, three-wire), physical range settings corresponding to 4mA and 20mA
- 0-10V Voltage Signal Sensors: Wiring methods, physical range settings corresponding to 0V and 10V
- Custom ADC (Analog-to-Digital Conversion): Introduce how to access 0-1.5V or other customized voltage signals, and the use of voltage divider resistors (such as 10KΩ and 1.5KΩ)
- Application of Analog Data in Automation Control
