Ds18b20 of single chip microcomputer temperature control system

The core of single chip microcomputer temperature control system

By the 895X series microcontroller to drive the 18B20 temperature sensor module, by writing the C language code, to achieve the control of the module driver, and constantly receive read 18b20 sent over the temperature signal. The transmitted high and low bits are converted into 10 binary numbers by processing the personal code to display in the LCD.

This single-chip microcomputer temperature control System Overview:

The system adopts single-chip microcomputer STC89C51RC as the main control, the crystal oscillator Y11.0592MHZ,LCD adopts the LCD12864, the temperature sensor adopts the 18B20 module, the buzzer as the key prompt tone, the key, and the XFS5152CE speech synthesis module as the temperature alarm sound, The 8-way level conversion module converts the 5v voltage into a 3.3v voltage, the horn plays the alarm sound, and the control of the relay is controlled to control a DC motor fan through-off.
