Lightning Sensor Module

amplifier

Use this lightning sensor module to detect approaching lightning strikes.

Part # LSM-1A Can sound a buzzer 2 seconds for each lightning strike detected.

Part # LSM-2A Can sound a buzzer 0.1 second for each lightning strike detected.

Part # LSM-3A Can sound a buzzer 0.01 second for each lightning strike detected and can be used for counting flashes up to 100 per second.

Strong thunder storms having a lot of lightning will cause a loud steady alarm to sound.

Simple 2 wire connection to a 9-volt battery and a buzzer.

Range up to 100 miles can be obtained.

Operates on 9 volts DC. Draws about 0.0001 uA (A 9-volt battery will last about 2 years of normal use).

Easy 3 wire connection: Yellow = Antenna , Output Red = (+), Black = (-).

It is input protected and overload protected.

Part # LSM-1A Can sound a buzzer 2 seconds for each lightning strike detected.
Part # LSM-1A $ 35.00 + $ 8.00 s/h.

Part # LSM-2A Can sound a buzzer 0.1 second for each lightning strike detected.
Part # LSM-2A (0.1 second alarm 'click') $ 35.00 + $ 8.00 s/h.

Part # LSM-3A Can sound a buzzer 0.01 second for each lightning strike detected and can be used for counting flashes up to 100 per second.
Part # LSM-3A (0.01 second alarm 'click') $ 35.00 + $ 8.00 s/h.

Support parts:

R1 = 2200 ohm resistor.
Buzzer = Any piezo buzzer for 6 to 9 volts. (30 mA max).
50 feet of cable. Any kind, but recommend flat thin telephone cable similar to the type on the unit.
Ground rod: 3 foot long copper rod.

Instructions:

Wire the unit as shown above.

The antenna and sensor module should be mounted away from power lines, phone lines, and trees.

Connect a 5 foot long vertical antenna wire to the yellow wire. The antenna tip should be 9 feet above ground. You can support the wire inside of a piece of CPVC pipe like shown below.

The antenna tip should not be higher than 9 feet above ground. If the antenna is too high then extreme range will result.

Any two wire type cable (best to use phone wire like on the unit), can run back indoors to your battery and buzzer unit.

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 directly under where the antenna is located. This will improve reception.

The antenna and sensor module can be placed inside of CPVC or PVC pipe fittings and clamped on to a metal pole using U-Clamps.

When power is first turned ON, the alarm will sound for about 2 seconds.

The lightning sensor module draws less power on standby than a wrist watch, so the battery will last about 2 years under normal use.

If the range is too great, then lower the antenna or use less antenna wire until desired range is obtained.

The 5 foot pole should be driven in the ground 1 foot for stability. Do not put this assembly on a tall pole or on your roof. Range will be too great.

Do not power the sensor module or alarm with wall plug-in power adapters: Detection of house electrical noise will result.
