DS1820 Based High Precision Temperature Indicator

This project is an High precision digital thermometer which indicates the temperature on the seven segment display. It has an resolution of 0.06deg.
The 1 wire temperature sensor IC from Maxim semiconductors is used as the sensor. The DS18S20 Digital Thermometer provides 9-bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of 0C to +125C.
In this project the negative temperatures are not taken so that it will display the temperature from 0deg to 99.9deg.
