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 9bit 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 55°C to +125°C. In this project the negative te
