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.

The picture above shows the basic design of the construction of this digital thermometer, you can see detailed explanations of this project here in pdf filetype (source: elec.gla.ac.uk)
