Under Voltage and Over Voltage Monitor for 5V

This module built using MC33161 IC, which is a universal voltage monitor intended to be used in a wide variety of voltage sensing applications. The project offers an economical solution for positive and negative voltage detection. The circuit consists of two comparator channels each with hysteresis, a unique Mode Select Input for channel programming, a pinned out 2.54 V reference, and two open collector outputs installed with LED for visual alert for under-voltage and over-voltage situations. The project is configured for a 5V supply by default. It provides a visual indication when supply is lower the 5V and over 5V. Yellow LED indicates undervoltage and Red LED indicates overvoltage. Trimmer potentiometers PR1 and PR2 were provided to adjust the Undervoltage and Overvoltage range. Both inputs can be used as independent or combined (Single Input)
