Temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensor is the core part of temperature measuring instruments and there are many varieties. Volgens de meetmethode, it can be divided into two categories: contact type and non-contact type. According to the sensor material and electronic component characteristics, it can be divided into two categories: thermal resistor and thermocouple.

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 Draad, and through 64-bit identity authentication, the temperature information collected from different sensors can be read separately.

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

PT100/PT1000 temperatuurregistratiecircuitoplossing

Metalen thermische weerstanden zoals nikkel, copper and platinum resistors have a positive correlation with the change in resistance with temperature. Platina heeft de meest stabiele fysische en chemische eigenschappen en is het meest gebruikt. The temperature measurement range of the commonly used platinum resistor Pt100 is -200～850 ℃. In aanvulling, the temperature measurement ranges of Pt500, Pt1000, enz. zijn achtereenvolgens verminderd. Pt1000, temperature measurement range -200～420 ℃. Volgens de IEC751 International Standard, De temperatuurkarakteristieken van de platina -weerstand PT1000 voldoen aan de volgende vereisten:
