| Type | Typical Range ( degreesC) | Accuracy | Output | Popular Brands |
|---|---|---|---|---|
| Thermistor | -40 to +125 | 0.1-2 degreesC* | Analog (resistance) | Vishay, EPCOS, Murata |
| RTD | -200 to +600 | 0.1-0.5 degreesC | Analog (resistance) | Omega, Amphenol, ABB |
| Thermocouple | -200 to +1370 | 0.5-2 degreesC | Voltage (mV) | Omega, Adafruit |
| Digital IC | -55 to +125 | 0.2-2 degreesC | Digital (I2C, 1-Wire) | Maxim (DS18B20), Microchip |
*Accuracy depends on curve, calibration, and interface electronics. For lab/medical uses, refer to datasheets for guaranteed tolerances.
A popular South African student experiment involves an NTC thermistor voltage divider circuit. Here's an example:
Vin [10kOhm]+[NTC Thermistor]GND
|
A0 (Analog Input)
Apply Ohm's Law (V = IR) and the Steinhart-Hart equation for accurate readings. Calculate temperature in degreesC using Arduino libraries or reference tables.
