A temperature sensor is a device that detects and measures heat energy from a physical environment and converts it into a readable electrical signal. It is essential for monitoring and controlling thermal conditions in various systems, from electronics to HVAC and industrial processes.
- Sensing Types: Thermocouple, RTD (Pt100/Pt1000), NTC/PTC thermistors, or semiconductor-based
- Operating Range: Varies by type; typically -50°C to +600°C
- Accuracy: High-precision models offer ±0.1°C to ±1°C
- Output Signal: Analog (voltage/resistance) or digital (I²C, SPI, 1-Wire)
- Probe Styles: Screw-in, immersion, surface mount, or contactless IR
- Material Construction: Stainless steel, plastic, or ceramic for different environments
- Applications: HVAC, refrigeration, solar systems, industrial control, battery monitoring, and electronics
