This temperature measuring project has a variety of range from -55 to +125 degree centigrade indicating on four common anode seven segment display module.The project measures an accurate temperature value point to point.
The main sensing part of the project is the semiconductor DS1820.It is based an one wire protocol device manufactured by Dallas semiconductor comes in different resolution such as DS18 S20(9-bit resolution), DS18B20 (12-bit resolution) etc.A microcontroller(AT89C2051) controls whole circuit function like receiving the serial data from DS1820 and converting the value for displaying the seven segment module.
