Practice making DIY- GC 00 155 - temperature curve display temperature temperature control system
1. Function description:
Design based on 51 single-chip microcomputer - temperature curve display temperature temperature control system
2. Function description:
STC89C52 single-chip microcomputer + LCD12864 display + DS18B20 temperature sensor + 1 red LED light to simulate heating + 1 green LED light to simulate cooling + 4 buttons (temperature lower limit addition and subtraction keys, temperature upper limit addition and subtraction keys)
1. The single-chip microcomputer reads the DS18B20 temperature sensor to obtain the temperature value, and then displays it on the LCD12864. And the temperature curve is displayed in the form of a curve, and the temperature curve can be moved.
2. You can set the temperature lower limit and temperature upper limit by pressing the button.
3. When the ambient temperature is lower than the lower limit, the heating red LED is on, and when the ambient temperature is higher than the upper limit, the cooling green LED is on. The temperature is not heating and cooling in the range of lower limit and upper limit.
