Instructions for Use

1. Mounting:

   • Ensure the sensor is mounted in a location that accurately reflects the temperature you wish to measure.
   • Avoid mounting near heat sources or in areas with high electromagnetic interference.

2. Wiring:

   • Connect the two leads of the sensor to your measurement circuit.
   • The positive lead should be connected to the power supply, and the negative lead should be connected to ground.

3. Calibration:

   • Measure the resistance of the sensor at a known temperature (e.g., 25°C) to calibrate your system.
   • Use the sensitivity (α) value to calculate the temperature based on changes in resistance.

4. Operation:

   • Apply a constant current to the sensor and measure the voltage drop across it to determine the resistance.
   • Convert the resistance to temperature using the formula: [ T = frac{R - R_0}{alpha} ] where ( T ) is the temperature, ( R ) is the measured resistance, ( R_0 ) is the resistance at 25°C, and ( alpha ) is the sensitivity.

5. Handling:

   • Handle the sensor with care to avoid damage.
   • Do not exceed the maximum operating voltage or temperature range to prevent damage to the sensor.

6. Storage:

   • Store the sensor in a dry, cool place to ensure its longevity.
