Frequently Asked Questions

What is the output signal of the Keyestudio LM35 module?

The module provides a linear analog voltage output. The output voltage increases by 10 millivolts (mV) for every 1°C rise in temperature. This signal can be directly connected to an analog input pin on an Arduino or other microcontroller for reading via its ADC.

What is the required power supply for this LM35 module?

The LM35 sensor itself can operate from 4V to 30V. This breakout module is typically designed for use with standard 5V microcontroller systems like Arduino. Ensure your power source is stable and within this range for accurate readings.

How do I connect and read data from this sensor with an Arduino?

Connect the module's VCC pin to Arduino 5V, GND to GND, and the analog output (Vout) to an analog input pin (e.g., A0). In your Arduino sketch, read the analog pin value, convert the voltage reading (0-1023 for a 5V reference) to millivolts, and then divide by 10 to obtain the temperature in Celsius.

What is the accuracy and measurement range of this sensor?

This LM35 module is rated for a temperature measurement range of 0°C to 100°C. It offers an accuracy of ±0.5°C at room temperature (typically 25°C). Accuracy may vary slightly at the extremes of its operating range.
