    LM35DT Typical application Circuitry Schematics

    LM35DT

    The LM35DT is a precision temperature sensor from Texas Instruments. It's calibrated directly in Celsius and has a linear +10 mV/°C scale factor. Here's a simple application circuit for the LM35DT: 

    1. Power Supply: Connect the V+ pin (pin 1) to a +5V supply and the GND pin (pin 2) to ground. 4V to 30V power supply are compatible with the LM35DT.
    2. Output: The output, which is proportional to the temperature, is provided by the VOUT pin (pin 3). This output voltage can be directly connected to an ADC input of a microcontroller for digital processing. For instance, the output voltage will be 250mV at a temperature of 25°C. 
    3. Decoupling Capacitor: It's recommended to connect a ceramic bypass capacitor (e.g., 0.1uF) close to the V+ and GND pins. This is to filter out any high-frequency noise on the power supply line. 
    4. Grounding and Layout: Accurate temperature measurement requires careful PCB layout. The sensor should be placed away from heat-generating components and any ground-return currents. Also, avoid running digital lines under the sensor IC since they can couple noise into the sensor. 
    5. Optional Calibration: While not required for most applications, you could include a calibration potentiometer in series with the output to adjust the output to compensate for any offset or gain errors in your specific system. 
    Always refer to the LM35DT datasheet for detailed information about wiring and application circuits. Be sure to design your circuit with careful consideration of grounding and routing to minimize errors due to electrical noise and heat sources.
