Čo je digitálny snímač teploty? Dizajn senzorovej sondy DS18B20

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 je bežne používaný digitálny snímač teploty, ktorý vysiela digitálny signál. Má vlastnosti malej senzorovej sondy, nízke požiadavky na hardvérový dizajn, silná schopnosť proti rušeniu a vysoká presnosť. Digitálny teplotný snímač DS18B20 sa jednoducho pripája, a môže byť použitý pri mnohých príležitostiach po zabalení sondy. Ako napríklad typ potrubia, závitový typ, typ magnetickej adsorpcie, typ balenia z nehrdzavejúcej ocele, rôzne modely, vrátane LTM8877, LTM8874, tam.
The appearance of the probe is mainly changed according to different application occasions. Zabalený DS18B20 je možné použiť na meranie teploty káblových výkopov, meranie teploty obehu vody vo vysokej peci, meranie teploty kotla, meranie teploty v strojovni, meranie teploty poľnohospodárskeho skleníka, meranie teploty v čistej miestnosti, ammunition depot temperature measurement and other non-extreme temperature occasions. Wear-resistant and collision-resistant, malá veľkosť, jednoduché použitie, various packaging forms, suitable for various small space equipment digital temperature measurement and control fields.
