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
Nastavljiva ločljivost: 9 – 12 bit; Temperaturno območje: -55 ℃ do +125 ℃; Izhod : rdeča (VCC), rumena (PODATKI), črna (GND)
Temperaturni senzor DS18B20: velikost ohišja iz nerjavečega jekla je pribl. 6 x 50 mm/ 0.2 x 2 palec, in digitalni temperaturni toplotni kabel ima skupno dolžino pribl 1 m/ 39.4 palec, ki je dovolj dolg, da zadosti vašim potrebam.
YAXUN DS18B20 temperature sensor is compatible with Raspberry Pi, in se pogosto uporablja pri spremljanju temperature kabelskega jarka, kotel, kaj, kmetijski rastlinjak, čista soba, itd.
