Temperature Sensor Selection<\/a><\/span><\/b><\/h2>\n

Four dominant sensor technologies cover virtually all thermal measurement applications: NTC thermistors (high sensitivity, \u221255\u00b0C to +150\u00b0C, low cost, requires linearisation); Platinum RTDs PT100\/PT1000 (best linearity and interchangeability, \u2212200\u00b0C to +850\u00b0C, \u00b10.15\u00b0C Class A accuracy, 4-wire Kelvin connection eliminates lead resistance); Thermocouples (widest range, up to +1,260\u00b0C Type K, requires cold-junction compensation); Digital temperature ICs (factory-calibrated, I\u00b2C\/SPI\/1-Wire output, \u00b10.1\u00b0C available, no external ADC or linearisation firmware needed). For BOM cost below USD 0.15 with a spare ADC channel: NTC. For accuracy < \u00b11\u00b0C without ADC design effort: digital IC. And for temperatures above +125\u00b0C: RTD or thermocouple.<\/span><\/p>\n

What Is a Temperature Sensor?<\/span><\/b><\/h2>\n

A temperature sensor is a transducer that converts ambient or contact temperature into a proportional electrical output \u2014 typically a resistance change, voltage, or digital code \u2014 enabling monitoring, control, and protection functions in electronic systems.<\/span><\/p>\n
