Lm358 Low Voltage Cutoff Circuit

When the input dc voltage is equal to the zener voltage the op amps output is approximately zero.

Lm358 low voltage cutoff circuit.

When the input voltage goes high then the relay will be activated and also when the input voltage is below then required level then relay activated. This dark sensor ic lm358 circuit is used to test a light dependent resistor a photo diode and a photo transistor. But you need to change a photo diode and the photo transistor in place. Applications of lm358 ic lm358 ic based dark sensor circuit.

And a voltage divider is used to divide voltage and connects its output at 4th number pin of pic microcontroller. You can use both ln324 or lm358 but i have shown lm358 in the diagram. Hi swagatam i have made schematic in multisim and simulate it but it cannot simulate as i intend. The lm258 lm258aand lm158 lm158acan be derated based on a 150 c maximum junction temperature.

This voltage sensor circuit can be used to protects any appliance to voltage fluctuation. Over voltage and under voltage protection circuit for high and low voltage cutoff. O p voltage swing is large. May be i connect something wrong.

Sensing voltage derived through the 10 k pre set is given to the non inverting ve terminal and this sets the high level cut. In a printed circuit board operating in a still air ambient. The power supply voltage and differential i p voltages are similar. When the input dc from the sensor is less than zener voltage the output of the op amp is low and vice versa.
