Temperature Sensors

Sensor	Range	Accuracy	Notes
NTC thermistor	−50 to 150 °C	±0.5–1 °C	cheap, non-linear, very sensitive
RTD (Pt100/Pt1000)	−200 to 600 °C	±0.1–0.3 °C	very stable, linear, needs excitation
Thermocouple (type K)	−200 to 1250 °C	±1–2 °C	~41 µV/°C, needs cold-junction compensation (MAX31855)
LM35 / TMP36	−40 to 150 °C	±0.5–2 °C	analog, 10 mV/°C
DS18B20, BME280	−55 to 125 °C	±0.5 °C	digital (1-Wire, I2C)

NTC thermistors follow the Beta equation:

$\frac{1}{T} = \frac{1}{T_0} + \frac{1}{B}\ln\frac{R}{R_0}$

with $T$ in kelvin, $R_0$ the resistance at $T_0$ = 298.15 K (25 °C).
