Analog-to-digital converter-based industrial fault indicator system that detects overvoltage and temperature

Abstract

In order to quantify the electrical properties of voltage, current, and resistance, it is necessary to construct analog circuits. The aforementioned analog circuits are capable of measuring three distinct parameters and subsequently generating corresponding outputs. The analog circuit outputs are intended to be linked to an ADC, which in turn is connected to a microcontroller for the purpose of acquiring the desired parameter. The program defines a predetermined set point for the temperature of the DC motor. When the temperature reading falls below this set point or exceeds it, the motor is activated. Likewise, the voltage can be determined by observing the green and red LED. Subsequently, the aforementioned readings have the capability to be exhibited on the liquid crystal display (LCD) screen.
