DS18B20 Temperature Sensor Module is defined as a 3-wire digital temperature sensor, with 9 to 12-bit resolution. These sensors easily connect to Arduino with only one 4.7K resistor, base 1 Ground 2 Output Base 3 to the positive of the source, with resistance to base 2 connected.
The 3-wire digital temperature sensor offers a fairly precise of ±0.5°C over much of the range. Hence the temperature with a precision of 0.0625 C was measured. It can give output digitally accurate to 12 bits of precision from the onboard digital-to-analogue converter. The sensor is connected to Arduino via the dedicated 1-wire protocol. As a result, several sensors can be connected only through one common wire to Arduino. Each one has a unique 64-bit ID burned in at the factory to differentiate them. Thus convert 12-bit data at a maximum conversion time of 750ms.
Moreover, this is the latest DS18B20 1-Wire digital temperature sensor operates with 3.0-5.0V systems providing 9 to 12-bit precision, at a Temperature measurement ranges of-55C to +125C, be accurate to 0.5C. When using with microcontroller put a 4.7k resistor to the sensing pin, required as a pullup from the DATA to the VCC line. Finally, the Alarm search command identifies and addresses devices whose temperature is outside of programmed limits.
