Darlington Pair Circuit. This circuit is a simple water level indicator wherein darlington pair is used as a switch. When the water level is not enough to close the sensor darlington transistor is in off state.
We know that this transistor configuration provides a large collector current so it is able drive the buzzer at the output. It consists of two bipolar transistors that are connected in such a way that the current amplifies by the first transistor then by the second transistor. The emitter of the input transistor is connected directly to the base of the second.
In electronics a multi transistor configuration called the darlington configuration commonly called a darlington pair is a compound structure of a particular design made by two bipolar transistors connected in such a way that the current amplified by the first transistor is amplified further by the second one.
A darlington transistor also known as a darlington pair is an electronics component made via the combination of two bjts bipolar junction transistor connected in such a way that it allows a very high amount of current gain. We know that this transistor configuration provides a large collector current so it is able drive the buzzer at the output. It normally consists of two transistors although in theory it can contain more. In electrical and electronic circuits darlington transistor or darlington transistor pair is an essential component.
