GND is the ground pin of the DS18b20 Temperature Sensor IC and it should be connected to the ground pin of the Arduino.ĭOUT is the Digital Output pin of the IC that uses the 1-Wire Protocol to give out the temperature data. VCC is the supply pin of the DS18b20 Temperature Sensor that can be connected to 3.3V or 5V of the supply. The Pinout of DS18b20 Temperature Sensor is as follows: The DS18b20 Temperature Sensor IC has 3 pins VCC, GND, and Digital Out. Not only is this sensor inexpensive and simple to use, but it also has a one-of-a-kind 1-wire communication protocol that is simple to build and supports a wide range of devices that can connect with the CPU.

There are a variety of sensors that may be used to solve this problem but in today's article, we thought to cover the DS18b20 temperature sensor. But one of the major disadvantages of the LM35 sensor is that it is analog in nature, so it's sensitive to external noise. 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.
