Description:
The KY-013 module simplifies temperature sensing by incorporating the necessary components onto a single board. It typically includes the LM35 (or equivalent) temperature sensor IC, along with passive components for signal conditioning. The module outputs an analog voltage that varies linearly with temperature, usually 10mV per degree Celsius. This analog signal can then be read by a microcontroller's ADC pin, allowing for precise temperature readings.
Key Features:
- Wide Temperature Range: Typically measures temperatures from -55°C to +150°C (depending on the specific LM35 variant used).
- High Accuracy: The LM35 provides accurate temperature readings, typically within a few degrees Celsius.
- Linear Output: The analog voltage output varies linearly with temperature, simplifying calibration and signal processing.
- Easy Interface: The module is designed for easy interfacing with microcontrollers and other analog devices.
- Low Power Consumption: The LM35 is a low-power device, making it suitable for battery-powered applications.
- Small Size: The module is compact and can be easily integrated into various projects.
- Cost-Effective: KY-013 modules are readily available and relatively inexpensive.

Important Notes:
- The accuracy of the KY-013 module depends on the specific LM35 variant used. Different variants have different temperature ranges and accuracy specifications.
- It's important to consult the datasheet for the LM35 variant on your specific KY-013 module to understand its exact specifications.
- The KY-013 module typically requires calibration to achieve the highest accuracy. This involves comparing the module's readings to a known temperature source.
- When interfacing with a microcontroller, an analog-to-digital converter (ADC) is used to convert the analog voltage output to a digital value that the microcontroller can understand.
