NTC (Koefisien suhu negatif) Sensor suhu adalah elemen pengukur suhu yang menggunakan penurunan eksponensial dalam resistansi termistor saat suhu naik. Inti adalah semikonduktor keramik yang dibuat oleh sintering logam oksida (seperti mangan, kobalt, dan nikel), dan suhu disimpulkan dengan mengukur perubahan resistensi. Berikut ini adalah karakteristik teknis intinya, aplikasi, dan poin seleksi:

The DS18B20 sensor communicates using the “1-Wire” protocol, which means it uses a single data line for all communication with a microcontroller, allowing multiple sensors to be connected on the same line and identified by their unique 64-bit serial code; this single data line is pulled high with a resistor and the sensor transmits data by pulling the line low during specific time slots to send bits of information.

This article explains in detail the application of custom DS18B20 digital temperature sensor in building a digital thermometer. Including working principle, hardware connection, software programming and simulation implementation. Provide complete protues simulation diagram, C source code and result analysis to help readers deeply understand and practice the use of DS18B20.
