How Does a DS18b20 Temperature Sensor Work and how to Interface it with Arduino?
In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule power for stable operation. But one of the major disadvantages of the LM35 sensor is that it is analog in nature, so it's sensitive to external noise.
