Usually a single LED that flashes with each discharge.

Simple schemas cannot distinguish between a weak nearby strike and a strong distant one. Both will trigger the indicator similarly.

Most versions of this schema use a high-gain transistor stage (often a Darlington pair or multiple stages) to amplify the tiny signal picked up by a telescopic or wire antenna [3, 4]. While sensitive enough to detect strikes from tens of kilometers away, they are prone to "false positives" from household appliances, thermostats, or light switches [4].

It is critical to note that these devices do not protect against lightning; they only indicate its presence. If used with an outdoor antenna, proper grounding and lightning arrestors are mandatory to prevent the device itself from becoming a fire hazard. Verdict

A piezo buzzer or a small speaker that produces a "click" or "crackle" sound.

The effectiveness depends heavily on the antenna length. A longer wire increases range but also increases the likelihood of picking up industrial noise [3]. Indication Method:

The (Lightning Indicator Circuit) is a popular DIY electronics project often featured in hobbyist literature and forums (like Radio magazine) designed to detect the electromagnetic pulses (EMP) generated by lightning strikes [2, 3]. Overview of the Circuit

These circuits are generally very efficient, often running on a 9V battery for months because they remain in a low-power "waiting" state until a signal is detected [2, 4]. Practical Limitations
