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 (na primer, GPIO4).
Connect a 4.7kΩ pull-up resistor between the data pin and the 3.3V power pin.

Rešitev vezja za zajem temperature PT100/PT1000

Kovinski toplotni upori, kot je nikelj, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platina ima najstabilnejše fizikalne in kemijske lastnosti in se najpogosteje uporablja. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. Poleg tega, the temperature measurement ranges of Pt500, Pt1000, itd. se zaporedno zmanjšujejo. Pt1000, temperature measurement range -200～420 ℃. V skladu z mednarodnim standardom IEC751, temperaturne značilnosti platinastega upora Pt1000 izpolnjujejo naslednje zahteve:
