Applications of LM358 IC

LM358 IC Based Dark Sensor Circuit

This dark sensor circuit using the LM358 IC can test a light-dependent resistor (LDR), photodiode, and phototransistor. To test different components, you simply replace the LDR with a photodiode or phototransistor. The dark sensor circuit using an LDR and LM358 IC is shown below. The required components to build this circuit include an LDR, LM358 IC, 9V battery, resistors (R1-330R, R2-1K, R3-10K), a variable resistor (VR1-10K), and a transistor (Q1-C547).

When a photodiode is used in place of the LDR, the circuit operates immediately. You can adjust the variable resistor to set the circuit's sensitivity based on the light level in the room.

Similarly, when a phototransistor is used instead of the LDR, the circuit also functions immediately. Adjusting the variable resistor will fine-tune the circuit's sensitivity according to the ambient light level.

LM358 IC Based Shock Alarm Circuit

The following circuit is a shock alarm circuit used in various applications, from homes to automobiles. Its primary application is in automobiles as an anti-theft alarm. In this circuit, a piezoelectric sensor is used as the shock sensor and must be fixed on the door you want to guard. Here, the LM358 is connected as an inverting Schmitt trigger. The threshold voltage of the circuit can be set by port1, and resistor R1 is used as a feedback resistor.

When the piezo sensor is not activated, the output of the sensor will be low. When the piezo sensor is triggered, its output goes high, activating the Schmitt trigger, which then sounds the buzzer. The buzzer continues to beep for a while, even if the vibration is detached. This occurs because when the inverting input increases, it has a minimal effect once the LM358 IC is activated, and the state can't be easily inverted.

• A 3-volt battery is used as the power supply in this circuit.
• Connect the sensor carefully to the surface where you arrange it.
• It is best to place the sensor near the door's handhold.
• Adjust the R2 resistor to achieve the desired sensitivity.
• Assemble the circuit using the required components on a good quality common board or printed circuit board.
• Use an IC holder to secure the IC.

Advantages of LM358 IC

• Two operational amplifiers are compensated internally.
• Two internally compensated op amps.
• Eliminates the need for dual supplies.
• Allows direct sensing near GND and VOUT.
• Compatible with all logic methods.
• Power drains suitable for battery operation.
