LM35

Product Description

The LM35 is an integrated circuit sensor that can be used to measure temperature with an electrical output proportional to the temperature (in oC)

  • Why Use LM35s To Measure Temperature?
    • You can measure temperature more accurately than a using a thermistor.
    • The sensor circuitry is sealed and not subject to oxidation, etc.
    • The LM35 generates a higher output voltage than thermocouples and may not require that the output voltage be amplified.
    • What Does an LM35 Do?  How does it work?
      • It has an output voltage that is proportional to the Celsius temperature.
      • The scale factor is .01V/oC
      • The LM35 does not require any external calibration or trimming and maintains an accuracy of  +/-0.4 oC at room temperature and +/- 0.8 oC over a range of 0 oC to +100oC.
      • Another important characteristic of the LM35DZ is that it draws only 60 micro amps from its supply and possesses a low self-heating capability. The sensor self-heating causes less than 0.1 oC temperature rise in still air.
    • How Do You Use An LM35?  (Electrical Connections)
      • Here is a commonly used circuit.  For connections refer to the picture above.
      • In this circuit, parameter values commonly used are:
        • Vc = 4 to 30v
        • 5v or 12 v are typical values used.
        • Ra = Vc /10-6
        • Actually, it can range from 80 KW to 600 KW , but most just use 80 KW.
