Electrical temperature sensors
- Thermistor- Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature. Negative Temperature Coefficient thermistors exhibit a decrease in electrical resistance when subjected to an increase in body temperature and Positive Temperature Coefficient thermistors exhibit an increase in electrical resistance when subjected to an increase in body temperature.
- Thermocouple
- Resistance thermometer
- Silicon bandgap temperature sensor
Integrated circuit sensors
In OpenBSD, many of the I²C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework since OpenBSD 3.9, which has also included an ad-hoc method of automatically scanning the I²C bus by default during system boot since 2006 as well.
In NetBSD, many of these I²C sensors are also supported and are accessible through the envsys framework, although none are enabled by default outside of Open Firmware architectures like
macppc
, and a manual configuration is required before first use on i386
or amd64
