Digital thermostat

[BenQ]

................... .......

Digital thermostat in this project design from microcontroller PIC16F628 .This circuit can control a outside system by driving a relay. For thermometer use DS1820 which is 1–Wire Digital Thermometer

Feature 
   
- LCD Temperature Display 
- Can control a outside system by driving a relay
- Can Adjust temperature

Hardware 
     Completed circuit of Digital Thermostat show in figure 1 . From figure 1 PIC16F628 is main device of circuit which keep source for control. DS1820 is thermometer which DS1820 is 1-wire thermometer . For temperature display use LCD Module 16X2 for display. Output can control outside by relay
