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

PT100/PT1000 temperatūras iegūšanas shēmas šķīdums

Metāla termiskie rezistori, piemēram, niķelis, Vara un platīna rezistoriem ir pozitīva korelācija ar pretestības izmaiņām ar temperatūru. Platīnam ir visstabilākās fizikālās un ķīmiskās īpašības, un tas ir visplašāk izmantotais. Parasti izmantotā platīna rezistora PT100 temperatūras mērījumu diapazons ir -200 ～ 850 ℃. Papildus, PT500 temperatūras mērīšana, PT1000, utt.. ir secīgi samazināti. PT1000, Temperatūras mērījumu diapazons -200 ～ 420 ℃. Saskaņā ar IEC751 starptautisko standartu, Platīna rezistora PT1000 temperatūras raksturlielumi atbilst šādām prasībām:
