Shema Indikatora Grozy Link

Because it is essentially a wide-band AM receiver, it lacks the sophisticated digital filtering found in professional detectors (like the AS3935 sensor), making it more of an educational tool than a precision safety device [4].

It is an excellent for students and electronics hobbyists to learn about radio waves and amplification. However, for serious meteorological monitoring or property protection, digital lightning sensors or professional weather data services are far more reliable. shema indikatora grozy

The circuit typically functions as a simple radio receiver tuned to very low frequencies (around 10–100 kHz), where lightning discharge energy is most concentrated [3]. Instead of playing audio, it triggers a visual or audible alert when it detects a surge. Because it is essentially a wide-band AM receiver,

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 The circuit typically functions as a simple radio

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].
