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; Plage de température: -55 ℃ to +125 ℃; Output : red (VCC), yellow (DATA), black (GND)
DS18B20 temperature sensor: the size of stainless steel housing is approx. 6 X 50 mm/ 0.2 X 2 pouce, and the digital temperature thermal cable has a total length of approx 1 m/ 39.4 pouce, which is long enough to meet your needs.
YAXUN DS18B20 temperature sensor is compatible with Raspberry Pi, and is widely applied in temperature monitoring of cable trench, boiler, zer, agricultural greenhouse, clean room, etc..

A temperature probe is a device used to measure temperature, usually consisting of a sensitive element and a measuring circuit. The sensitive element can be a thermocouple (pt100, pt1000), a thermal resistor (ntc, ptc), a semiconductor (DS18B20 digital), etc., which can convert temperature changes into electrical signals. Then it is amplified, filtered, converted, and processed by the measuring circuit, and finally an electrical signal proportional to the temperature is output.
