How does a Lightning Detector work?

How do weather reporters give information regarding thunders and lightning beforehand? They give you the information they got from a lightning detector. There is a mysterious phenomenon behind lightning and the detector. This device doesn’t give exact information but helps detect before, which helps people be careful. Unfortunately, many devices fail to give the exact prediction, but nature is always unpredictable. If you are curious about lightning and how a detector works, read this article.

What is a Lightning Detector?

A Lightning detector is a weather forecasting device that detects lightning produced during thunderstorms. It is a powerful electric bolt from thunders when there is a difference in electrical charge in a thunderstorm cloud.

This device can only detect, but the results can only sometimes be accurate as nature is unpredictable. This device helps by alerting the people from a deadly thunderstorm’s lightning.

These monitors can detect strikes from 40 miles away and give an accurate prediction. This device plays a major role in weather forecasting.

Types of Lightning Detector:

A lightning detector helps to detect the lighting caused by a thunderstorm. There are four basic types of detectors. They are,

Ground-based detector:

A Ground-based detector uses multiple antennas to detect lightning strikes. The strike’s direction detects using the radio direction techniques and the frequency characteristic.

This type of detector uses the triangulation of antennas from various locations to find the distance.

Ground-based detector tends to fail to find the number of strikes. One antenna detects the direction, and the other is still receiving.

Mobile Detectors:

Mobile detectors also help detect the direction and severity of a strike. It finds the direction by using the antennas in the same location.

Portable detectors’ antennas follow the ground-based triangulation method, which leads to giving detection of weak signals.

Space-based Lightning detectors:

Space-based detectors have fewer limitations than ground-based and portable detectors. But the information from this detector needed to be on time. This is the reason why these detectors are avoided for real-time uses.

Personal detectors:

These detectors are battery-based devices that are portable. These devices are popular among golfers, sports officials, etc., for checking thunderstorms and lightning strikes.

This device measures the electromagnetic field emitted by the strikes and gives its prediction. It cannot give the direction of the strike, location which is different from professional detectors.

How does a Lightning detector work?

A lightning detector is mainly used to detect the characteristics of a lightning strike, a thunder. There are different kinds of detectors, and they have their respective function.

Some detectors give predictions, and some give the location and direction of the strike too. The working of a detector is in three steps.

Detecting a strike: 

The lighting strike is caused due to the bolts in an electric field in thunderstorm clouds. Whenever lightning gives radio waves in the electric field, the device setup detects the radio waves immediately.

The antennas in the setup easily detect the waves because they are strong bolts. The antennas are placed in different locations, giving pulses whenever lighting is detected. Some antennas may receive pulses slowly because of the location of the sensors.

Locating the strikes:

Finding the location of a strike is important to find the time of the strike. Let’s say the detector has three sensors in different locations.

One sensor receives the pulse faster than the other because of their locations. A hyperbola is indicated to show the different times of the pulses. The common interaction of the hyperbolas is the location of the strike.

Transmitting data and alerting:

Once we find the location and time of the strike, now it needs to send the data. The cylindrical sensors of the detectors have a circuit board that converts the analog data into digital signals.

These digital signals give data about the lighting strike and help for alerting.

Importance of Ligtining detection:

Lighting strokes from thunderstorms have current, which is dangerous for living beings. It is deadly because a lighting strike can kill plants, animals, and humans.

It is important to know about the strikes beforehand. Knowing the time and location makes it easy to alert and avoid the lighting.

A Lighting detector is a device that helps detect the time and location of the strike. Even though many predictions are accurate and cannot give exact data, it is safe to be alert.

Weather forecasters give accurate information about the strikes and predict the lighting location and time.

Applications of a Lightning Detector:

The applications of a Lighting detector are,

  • It is used before participating in sports activities.
  • While boating
  • Lightning detection is done for airport operations and safety.
  • It is helpful for revenue and park operational works.


The radio waves cause a Lightning detector to strike in the electric field of thunderstorms. This is deadly because it possesses a current that can damage and kill things. Knowing about the lighting strikes beforehand is always safe while participating in sports activities, boating, and flight travelling. The Lighting detector can detect strikes. This device detects the radio waves by the sensors through the triangulation method. This article gives you details about the detection of strikes.
