Digital Thermometers (PIC)
 
     Digital Thermometers in this circuit design from microcontroller PIC16F628 of micrichip company.Good point of PIC16F628 such as brown-out reset , low-voltage programming reference voltafe module,USART: Universal Synchronous Asynchronous Receiver Transmitter
  

PWM (CCP : Capture Compare Pulse-width modulation module

PIC16F628
     For completed circuit of Digital Thermometers show in figure 1 . It can be display 2 digit which you can applied to 3 digit
   
Figure 1. Schematics of   Digital Thermometers (PIC)
     For temperature sensor use IC DS1820 which The DS18S20 communicates over a 1-Wire bus. You can download data sheet from hardware Support Data
