DS18B20 Digital Temperature Sensor Connect Arduino

Today I will show you how to use the DS18B20 digital temperature sensor with an Arduino so you can measure the temperature of air, liquids such as water, and the ground.
To connect the DS18B20 digital temperature sensor to Arduino, you need to do the following steps:
‌Hardware connection‌:
Connect the VCC pin of DS18B20 to the 3.3V power pin of Arduino.
Connect the GND pin of DS18B20 to the ground pin of Arduino.
Connect the data pin of DS18B20 to the GPIO pin of Arduino (например, GPIO4).
Connect a 4.7kΩ pull-up resistor between the data pin and the 3.3V power pin.

Решение для схемы измерения температуры PT100/PT1000

Metal thermal resistors such as nickel, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platinum has the most stable physical and chemical properties and is the most widely used. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. Кроме того, the temperature measurement ranges of Pt500, Пт1000, и т. д.. are successively reduced. Пт1000, temperature measurement range -200～420 ℃. According to the IEC751 international standard, the temperature characteristics of the platinum resistor Pt1000 meet the following requirements:
