What is DS18B20?
The DS18B20 is one type of temperature sensor and it supplies 9-bit to 12-bit readings of temperature. These values show the temperature of a particular device. The communication of this sensor can be done through a one-wire bus protocol which uses one data line to communicate with an inner microprocessor.
Is DS18B20 digital or analog?
DS18B20 is 1-Wire interface Temperature sensor manufactured by Dallas Semiconductor Corp. The unique 1-Wire® Interface requires only one digital pin for two way communication with a microcontroller.
What type of sensor is a DS18B20 temperature?
direct-to- digital temperature sensor
Operation—Measuring Temperature The core functionality of the DS18B20 is its direct-to- digital temperature sensor. The resolution of the tempera- ture sensor is user-configurable to 9, 10, 11, or 12 bits, corresponding to increments of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C, respectively.
Is DS18B20 a body temperature sensor?
… user measures the body temperature by touching the temperature sensor. Figure 2 shows the DS18B20 temperature sensor utilized in this work. This sensor can measure temperatures between temperature ranges of -55 [°C] to +125 [°C] and is accurate to ± 0.5 [°C], over the range of -10[°C] to +85 [°C]. …
What is temperature sensor in Arduino?
The temperature sensor in Arduino converts the surrounding temperature to voltage. It further converts the voltage to Celcius, Celcius to Fahrenheit, and prints the Fahrenheit temperature on the LCD screen.
What is the output of DS18B20?
The resolution of the DS18B20 is configurable (9, 10, 11, or 12 bits), with 12-bit readings the factory default state. This equates to a temperature resolution of 0.5°C, 0.25°C, 0.125°C, or 0.0625°C.
How to print data from DS18B20 sensor to Arduino?
Before you start, download and unzip the following libraries at /Progam Files (x86)/Arduino/Libraries (default), in order to use the sensor with the Arduino board. To print the data from DS18B20 on the serial monitor of the IDE you have to build the circuit by following the schematic.
What is DS18B20 temperature sensor?
Step 1: Information About The Sensor. DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees in Celsius with 9 to 12-bit precision, from -55 to 125 (+/-0.5). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus.
