Hardware connection method
When connecting DS18B20 to a microcontroller, you need to follow the following basic steps:
Determine the pin function: DS18B20 has three pins, namely VDD (power), DQ (data line), GND (ground line).
Power connection: The VDD pin is connected to a 3.3V or 5V power supply, depending on the operating voltage of the microcontroller.
Data line connection: The DQ pin is connected to VCC through a pull-up resistor (typical value is 4.7kΩ).
Ground connection: The GND pin is directly connected to the ground line of the microcontroller.
The temperature sensor supports the “one-wire bus” interface (1-Wrie), the measurement temperature range is -55 °C ~ +125 °C, in the range of -10 °C ~ +85 °C, the accuracy is plus or minus 0.5 °C
Adjustable resolution: 9 – 12 bit; Temperature range: -55 ℃ to +125 ℃; Output : red (VCC), yellow (DATA), musta (GND)
DS18B20 temperature sensor: the size of stainless steel housing is approx. 6 x 50 mm/ 0.2 x 2 tuumaa, and the digital temperature thermal cable has a total length of approx 1 m/ 39.4 tuumaa, which is long enough to meet your needs.
