    STLM20W87F Typical application Circuitry


    STLM20W87F is a temperature sensor chip manufactured by STMicroelectronics. It offers precise temperature measurement with an accuracy of ±1.5°C. This chip has an analog voltage output and operates within a wide temperature range of -55°C to +130°C. The gadget is made to be used in a variety of situations where temperature sensing is essential.


    Applications for STLM20W87F can be found in a variety of industries, including consumer electronics, automotive, and industrial automation.

    Typical use cases consist of the following:

    1. Temperature Monitoring in Industrial Equipment: STLM20W87F can be used to monitor the temperature of machinery and equipment in industrial settings to ensure they operate within safe temperature ranges.

    Circuit Connection:

    To connect the STLM20W87F temperature sensor to a microcontroller, follow these steps:

    1. Power Supply (Pin 1): Connect Pin 1 (VCC) of STLM20W87F to a suitable power supply voltage between 2.7V and 5.5V.

    2. Ground (Pin 2): Connect Pin 2 (GND) to the ground (0V) of your power supply.

    3. Analog Output (Pin 3): Connect Pin 3 (OUT) to one of the analog input pins of your microcontroller.

    Design Considerations:

    When designing a circuit with STLM20W87F, consider the following:

    1. Calibration: The sensor may require calibration to achieve high accuracy in specific applications.

    2. Noise and Interference: Shield the sensor from electromagnetic interference (EMI) and minimize noise in the analog output signal path.

    3. Temperature Range: Ensure that the operating temperature range of the chip aligns with the application's requirements.

    4. Voltage Levels: Verify that the voltage of the power source falls within the designated range.

    5. Data Conversion: To convert the analog output of the sensor into a digital temperature value, use an analog-to-digital converter (ADC) built into your microcontroller.

    6. Filtering: Implement filtering techniques if necessary to remove noise from the sensor output.

    7. Data Handling: Develop software to process and interpret the temperature data from the sensor for your specific application.

    8. Environmental Considerations: Take into account any environmental factors that might affect temperature readings, such as airflow or nearby heat sources.

    By addressing these considerations, you can design a robust circuit using the STLM20W87F temperature sensor to meet the needs of your application.
