EXPERIMENT-8 Sensor Interface

This experiment was based on getting input of various sensors using ADC and display the output on DSO using DAC. Digital-to-Analog converters (DACs) and Analog-to-Digital converters (ADC) are important building blocks which interface sensors (e.g. temperature, pressure, light, sound, cruising speed of a car) to digital systems such as microcontrollers or PCs. An ADC takes an analog signal and converts it into a binary one, while a DAC converts a binary signal into an analog value.Applications for DACs span a wide range, from consumer audio to precision instrumentation, and everything in between. A DAC produces a set of analog values that corresponds to the digital input codes. Many DAC designs are actually current output devices, instead of voltage output devices.
