DS18B20 Temperature Sensing Wire Stainless Steel Probe Kit

Design of DS18B20 Digital Temperature Sensor for STM32

DS18B20 is a digital temperature sensor that uses a single bus timing to communicate with the host. Only 1 Wire is needed to complete the temperature data reading;
DS18B20 has a built-in 64-bit product serial number for easy identification. Multiple DS18B20 sensors can be connected to 1 Wire, and through 64-bit identity authentication, the temperature information collected from different sensors can be read separately.

PT100/PT1000 temperature acquisition circuit solution

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 ℃. In addition, the temperature measurement ranges of Pt500, Pt1000, etc. are successively reduced. Pt1000, temperature measurement range -200~420 ℃. According to the IEC751 international standard, the temperature characteristics of the platinum resistor Pt1000 meet the following requirements:
