Mis on digitaalne temperatuuriandur? DS18B20 andurisondi disain

A digital temperature sensor is a device that measures temperature and converts it into a digital reading that can be input into a microcontroller or other logic device. DS18B20 Digital temperature sensors use integrated circuits to provide accurate temperature readings. They are often used in consumer electronics, such as digital thermometers. DS18B20 on tavaliselt kasutatav digitaalse temperatuurianduri sondi kiip, mis väljastab digitaalsignaali. Sellel on väikese anduri sondi omadused, madalad riistvara disaininõuded, tugev häiretevastane võime ja kõrge täpsus. Digitaalset temperatuuriandurit DS18B20 on lihtne ühendada, ja seda saab kasutada mitmel korral pärast sondi pakkimist. Näiteks torujuhtme tüüp, keermestatud tüüp, magneti adsorptsiooni tüüp, roostevabast terasest pakendi tüüp, erinevaid mudeleid, sealhulgas LTM8877, LTM8874, jne.
The appearance of the probe is mainly changed according to different application occasions. Pakendatud DS18B20 saab kasutada kaablikraavi temperatuuri mõõtmiseks, kõrgahju veeringluse temperatuuri mõõtmine, katla temperatuuri mõõtmine, masinaruumi temperatuuri mõõtmine, põllumajandusliku kasvuhoone temperatuuri mõõtmine, puhta ruumi temperatuuri mõõtmine, ammunition depot temperature measurement and other non-extreme temperature occasions. Wear-resistant and collision-resistant, väike suurus, lihtne kasutada, various packaging forms, suitable for various small space equipment digital temperature measurement and control fields.

Hardware connection method
When connecting DS18B20 to a microcontroller, you need to follow the following basic steps:
‌Determine the pin function‌: DS18B20 has three pins, namely VDD (power), DQ (data line), GND (ground line)‌.
‌Power connection‌: The VDD pin is connected to a 3.3V or 5V power supply, depending on the operating voltage of the microcontroller‌.
‌Data line connection‌: The DQ pin is connected to VCC through a pull-up resistor (typical value is 4.7kΩ).
‌Ground connection‌: The GND pin is directly connected to the ground line of the microcontroller‌.
