Features
*Temperature range -55.0C to 125.0C (0.1 degree resolution)
*Both Celsius & Fahrenheit temperature formats
*4 bit LCD mode
The design has used 1 wire protocol for DS18S20 temperature sensor by maxim.
The temperature result format by DS18S20 was extended to 12 bit format. From this 12bit format one decimal point has been calculated.
Hardware
DS18S20 sensor configured as an external power supply mode & LCD configured as 4 bit mode to minimize the wirings. The whole circuit can work from a 5V source smoothly.
