1. The Role of Temperature Sensors in Fan Systems
1.1 What Are Temperature Sensors?
Temperature sensors are electronic devices that measure thermal conditions and convert them into electrical signals. Common types include:
- Thermistors – Resistance changes with temperature.
- RTDs (Resistance Temperature Detectors) – Provide precise measurements.
- Thermocouples – Generate voltage based on temperature differences.
- Infrared (IR) Sensors – Measure surface temperature without contact.
1.2 How Temperature Sensors Work in Fans
Fans equipped with temperature sensors use real-time thermal data to adjust their speed (RPM) automatically. The process involves:
1. Temperature Detection – The sensor measures ambient or component temperatures.
2. Signal Processing – A microcontroller interprets the sensor data.
3. Fan Speed Adjustment – The fan increases or decreases RPM based on cooling needs.
4. Feedback Loop – Continuous monitoring ensures stable thermal conditions.
