Voltage Level Detector

Voltage level detector circuit simulation response.

Voltage level detector. To see if the circuit is working or not use a potentiometer connect its two ends to the two poles of the battery connect the wiper to the first stage of the circuit. Built sensor tough ideal for situations where power quality is an issue voltagewatch sensors facilitate monitoring of supply voltage levels. It can be a simple pen shaped piece of testing hardware that indicates the existence of electricity or an advanced tool that detects precise voltage levels in electrical systems. Voltage level detectors operational amplifiers are often used in circuits in which the output is switched between the positive and negative saturation voltages v o sat and v o sat the actual voltage change that occurs is known as the output voltage swing for many op amps the output saturation voltages are typically the supply voltage levels minus 1 v.

Now as the potentiometer is swiped across its range a count can be observed represented by the four led s.
