Instructions for Using LM35DT

  1. Power Supply:

    • The LM35DT operates over a wide range of supply voltages from 4V to 30V.
    • Ensure the supply voltage is within the specified range to avoid damage.
  2. Temperature Measurement:

    • The output voltage of the LM35DT is directly proportional to the temperature in Celsius.
    • The typical sensitivity is 10 mV/°C.
    • For example, at 25°C, the output voltage will be 250 mV.
  3. Circuit Connections:

    • Connect the positive terminal (VCC) to the power supply.
    • Connect the negative terminal (GND) to ground.
    • The output terminal (VOUT) provides the temperature-dependent voltage.
  4. Output Filtering:

    • To reduce noise, a 10 μF capacitor can be placed between the output and ground.
  5. Thermal Considerations:

    • The thermal response time is approximately 250 ms.
    • Place the sensor in direct contact with the surface whose temperature you are measuring to ensure accurate readings.
  6. Operating Temperature Range:

    • The sensor can operate from -55°C to 150°C.
    • Ensure the sensor is not exposed to temperatures outside this range to prevent damage or inaccurate readings.
  7. Calibration:

    • The sensor is factory-calibrated and typically does not require additional calibration.
    • If necessary, calibration can be performed by comparing the output voltage to a known temperature reference.
  8. Handling:

    • Handle the sensor with care to avoid physical damage.
    • Avoid exposing the sensor to extreme environmental conditions such as high humidity or corrosive gases.

By following these instructions, you can ensure accurate and reliable temperature measurements using the LM35DT.
