This article is about a simple 0-100 C digital thermometer with 1 C resolution using 8051. The circuit is based on LM35 analog temperature sensor, ADC0804 and AT89S51 microcontroller. LM35 is an analogue temperature sensor IC which can measure a temperature range of -55 to 150 C. Its output voltage varies 10mV per C change in temperature.

For example, if the temperature is 32 C, the output voltage will be 32 x 10mV = 320mV. ADC 0804 is used to convert the analogue output voltage of the LM35 to a proportional 8 bit digital value suitable ....etc

Abstract:
In this project we attempt to design a simple ADC/DAC card which can be easily interfaced with 8085 microprocessor kit for Data Acquisition(DAQ) purposes. We extent our work by designing a pcb

APPLICATION:
Commerical ADC/DAC cards can cost hundreds of dollars, not viable for teaching purposes. This ADC/DAC card, which is much cheaper can be used ....etc

ABSTRACT

A pipelined analog-to-digital converter (ADC) architecture suitable for high-speed (150 MHz), Nyquist-rate A/D conversion is presented. At the input of the converter, two parallel track-and-hold circuits are used to separately drive the sub-ADC of a 2.8-b first pipeline stage and the input to two time-interleaved residue generation paths. Beyond the first pipeline stage, each residue path includes a cascade of two 1.5-b pipeline stages followed by a 4-b backend folding ADC. The full-scale residue range at the output of the pipeline ....etc

i need to store real time values of an circuit output which varies from 5v to 24 v in a micro controller 8051 but my prob is as micro controller takes only digital values i need to use an ADC to convert but the limitation of ADC s 5v what can i do to capture the real time values. ....etc

introduction
Digital thermometer is a good choice for beginners who just left the world of microcontrollers, because it provides an opportunity to learn using sensors to measure real world signals are analog in nature is. This article describes the project as based on microcontroller and temperature sensor LM35 PIC16F688. Is analogous to the LM35 sensor that converts the temperature to a proportional analog voltage. The output signal from the sensor is connected to one of the inputs of the ADC in a PIC16F688 microcontroller to obtain an equival ....etc
