The same procedure will be followed for other batteries. The LM324 has Vcc of 5V, the signal it gets from the sensor goes from 0-8V under its normal operating range, and if it goes beyond either limit for unseen reasons, I want the LM324 to take in instead of the micro controller. Now for the final voltage level set 6.25V in the power supply and adjust VR4 until LED4 turns off.Īfter these settings check all the voltage levels again by increasing the voltage to 6.3V in the supply and then lowering it slightly to make sure that all the LEDs are turning ON/OFF at their specific level. Now change the voltage of the power supply to 6.2V and adjust the VR3 until LED3 turns off. Now change the voltage of the power supply to 6.1V, and again adjust the VR2 until LED2 turns off. If you were using a 6V battery then set the voltage of the power supply to 6V. Replace the battery of the circuit with this power supply. Circuit Adjustmentsīefore using this circuit needs some tuning and requires a variable power supply. In this circuit, we are using a variable resistor of 10K at the input of each op-amp. pinout-datasheet-and-featuresid139 Lm324N Datasheet Pdf WebWeb download the. This voltage is set by variable resistors. SnapEDA is a free library of symbols & footprints for the LM324N by. Each op-amp in this circuit is working as a comparator separately to monitor a specific voltage of the battery being monitored. LM324 IC Features The features of this IC include the following.
