Temperature Sensors

Temperature Sensors

Temperature sensors convert ambient or surface temperatures into electrical signals. They are used in many areas, from industrial automation to smart home systems. The common sensor types and their characteristics are listed below.

Main Sensor Types:

• Thermocouple: Consists of two different metals. Ideal for high-temperature measurements. Can be used in a very wide temperature range.

• Thermistor (NTC/PTC): Semiconductor sensors whose electrical resistance changes with temperature. Commonly used in boilers and electronic devices for temperature control.

• RTD (Resistance Thermometer): Based on the resistance of metals such as platinum to temperature changes. Possesses very high sensitivity and stability. For example, PT100 sensors can measure temperatures between -200 °C and 850 °C.

Applications of Temperature Sensors:

• HVAC (Air Conditioning): Monitoring of ambient temperature and radiators.

• Process control: Temperature control in factories, furnaces, or liquid tanks.

• Embedded systems: Digital heat and humidity sensors for projects like Arduino or Raspberry Pi.

• To select the right sensor for your needs, you need to determine the maximum and minimum temperatures of the environment to be measured, as well as your budget.

• If you describe the device to be measured, the temperature range, or the application in more detail, I can give you more precise recommendations for the most suitable sensor type or model.
