Long range lightning sensor unit

lightning sensor

This patented long range lightning sensor is the start of your independant lightning alarm system. This lightning sensor can give you early warning of approaching lightning and severe storms.

This sensor draws ZERO battery power unless lightning is detected, making it easy on your survival circuits and battery. A 9 volt battery will power this sensor for over 2 years of 24/7 round-the-clock monitoring.

The sensor can connect to LED's, Buzzers, Relays, etc, to activate them when lightning is detected.

Easy 2 wire connection. Sensor acts like an ON-OFF switch in a circuit, turns ON briefly when there is lightning detected.

A buzzer or siren alarm you supply can sound up to 1 second for each lightning detection. Severe storms cause continuous activation.

Simply mount the sensor on a 10 foot pole outdoors, and connect with any 2-conductor wire to your buzzer and 9-volt battery.

Adding a ground rod will increase range.

Detects cloud-to-ground lightning up to 50 miles away if mounted on a 10 foot pole. The higher you mount it, the more range you will have. 15 feet gives 100 miles.

Detects the reliable ground-hugging VLF Very Low Frequency Sferic Waves emitted by cloud-to-ground lightning flashes.

Overload protected, reverse polarity detected, static protected.

There are not any pingable chips in this one.

How To Use The Lightning Sensor

Wire the unit as shown above.

The sensor should be mounted on a 10-foot tall pole away from power lines, phone lines, and trees.

Do not mount the sensor indoors, or in your attic, building materials may reduce the VLF sfreric waves, reducing the range greatly.

The sensor should not be mounted higher than 20 feet above local ground. If the sensor is mounted too high then extreme detection range is possible and will result in detecting storms outside your area, up to 300 miles away!

Any two wire cable can run back indoors to your 9-volt battery alarm circuit.

Connect a ground wire to the black wire on the sensor and connect to a ground rod (a 3 foot long piece of copper pipe) driven in the ground next to the mounting pole.

When power is first turned ON, the alarm will sound for about 1 second.

The lightning sensor draws no power on standby so the battery will last about 2 years under normal use when powering a piezo type buzzer.

If the range is too great, then lower the sensor.

Mount the unit on a 10 foot pole outdoors. Connect to a buzzer and 9-volt battery. The resistor across the buzzer is 10 K-ohms value and can be omitted You can power a 12 volt security-type siren with the sensor also.

The sensor can operate with up to 18 volts. Lowest operating voltage is 5 volts. Recommended volt range is 7 to 14 volts DC.


Lightning Sensor Tester:

Use this tester to check alarm operation. Simply shake it near the lightning sensor to make 'artificial sfreric waves' to test the sensor.
