About Temperature Sensors

A temperature sensor is a device that measures temperature and outputs a corresponding signal in either analog or digital format. For a deeper dive, check out [temperature sensor basics and types](linkto_your_article_here - _replace with actual link if you have it).

When choosing a temperature sensor for a specific application, consider the following key specifications:

  • Temperature Range: The range of temperatures the sensor can accurately measure.
  • Output Voltage: The output voltage level in mV corresponding to the measured temperature.
  • Accuracy/Tolerance: The degree of accuracy or acceptable error in temperature measurement.
  • Supply Voltage: The required voltage to power the sensor.
  • Sensor Gain: The average slope of the output voltage change with respect to temperature change, typically measured in mV/°C.
  • Load Regulation: The change in output voltage in response to a change in load current (mV/mA).
  • Line Regulation: The change in output voltage in response to a change in input voltage (mV/V).
