Temperature Sensor Circuit Design. Where to use ds18b20 sensor. A temperature circuit measures the temperature of the immediate environment and presents the value in a digital display.
In circuit design thermocouple rtd thermistor and ic temperature sensors are vital to the performance of every electronic circuit. In module 2 you will learn how to design a complete temperature sensor system within a development kit environment. Instead a temperature display circuit involves a temperature sensor microcontroller and a digital display.

Where to use ds18b20 sensor. The resolution of the temperature sensor is user configurable to 9 10 11 or 12 bits corresponding to increments of 0 5 c 0 25 c 0 125 c and 0 0625 c respectively. Pc0 pc5 pins of atmega8 act as adc channels. The circuit uses an op amp in a non inverting configuration with inverting reference to offset.
