Αρχεία ετικετών: DS18B20 1-Wire Digital Temperature Sensor

The DS18B20 sensor communicates using the “1-Σύρμα” 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.
