Do Design and Construct Yourself a Digital Thermometer Part II
As previously article discussed about digital thermometer, the following article will provide you with information 
regarding how to design complex circuits using op amps and practice PSpice skills in addition of building a digital thermometer.
In the depth of this diy digital thermometer article, you will be taken into section in designing and building a circuit that convert a temperature-sensitive resistance into a voltage scaled so that 1 F= 0.1V, then a scaled digital temperature reading can be read on the digital multimeters from the voltage (e.g. 72F will read 7.2 volts).
Do Design and Construct Yourself a Digital Thermometer
The following article will describe you with how to design and build a digital 
thermometer by yourself. The thermometer will show ambient temperature in degrees centigrade on a two digit LED display.
There are descriptions about the circuit design of the digital thermometer and the principles it uses, how and why the components were chosen, detailed sub-section circuit of the thermometer (temperature sensor, ramp generator, comparators, clock, counter, display, control logic), and then the design and construction strategy to be followed.
