Infrared sensors find numerous applications in electronic systems. Commonly used as an obstacle detector, its output is used in digital form (logic high and low) using a comparator. Infrared sensors find numerous applications in electronic systems. Commonly used as an obstacle detector, its output is used in digital form (logic high and low) using a comparator. This topic explains how to use the sensor output in its original analog form. Thus, along with the detection of an obstacle, its exact distance can also be obtained. This is achieved by processing the output of the IR sensor through an ADC0804 (analog-to-digital converter). The ADC is calibrated to obtain an almost accurate distance measurement.
The measured distance is also displayed on an LCD. The ADC0804 and LCD are interconnected with the 8051 microcontroller (AT89C51) to perform these operations. The main drawback of IR-based sensors is their ability to detect short distances.
