Flame Sensor Circuit Diagram

By | June 13, 2022



Are you looking to build a flame sensor circuit to detect the presence of flame or fire? You’ve come to the right place. In this article, we will attempt to map out a basic flame sensor circuit diagram. After reading, you should have a better understanding of how to construct your own circuit.

A flame sensor circuit detects the presence of a flame by using an optical sensing device. The sensor picks up infrared radiation emitted by the flame. The radiation is then processed and used to trigger an alarm.

The first step in your flame sensor circuit is to connect the power source. This could be either AC or DC. Then, you will need to connect the IR receiver or photodiode. This component is sensitive to infrared radiation and is used to detect the presence of a flame.

Next, connect the amplifier. This amplifies the signal from the IR receiver and sends it on to the next component. After the amplifier, connect the comparator. This is an important part of the circuit, as it compares the signal from the amplifier to a predetermined value. If the signal is above the value, an alarm is triggered.

Finally, you will need to connect the output component. This will be the alarm itself. This can be anything from an LED to a buzzer. Just make sure it is loud enough that it will alert the user when a flame is detected.

With the above components connected, your flame sensor circuit should be complete. It is important to test the sensor to ensure that it is working correctly. Once the test is complete, you should be ready to start using your flame sensor!

Creating a flame sensor circuit is a great way to keep yourself and your property safe. With a good plan, the right components, and a bit of elbow grease, you can easily build your own flame sensor circuit.
