We designed a DIY Lightning Safety gadget utilizing Arduino Nano, Relay, and an AS3935 sensor that may aid you defend digital units towards thunder-lightning.
Resulting from lightning, more often than not our digital units and residential home equipment obtained broken. The excessive voltage and present related to lightning may cause extreme injury if correct precautions usually are not taken.
Listed below are a couple of causes digital units might be broken by lightning:
Direct Strike: If a lightning bolt immediately strikes a constructing or an influence line related to the constructing, the excessive voltage surge can enter {the electrical} system and injury related units. That is extra more likely to happen if the constructing lacks correct grounding or surge safety measures.
Energy Surges: Lightning strikes close by can induce energy surges within the electrical grid. These surges can journey via energy traces and injury digital units related to them. Surges can enter units via energy retailers, telephones, cable TV, or community connections.
Electromagnetic Interference: The electromagnetic fields generated by lightning can induce sturdy currents in close by conductors, together with wires and circuits of digital units. These induced currents can disrupt regular operation and injury delicate parts.
To guard digital units from lightning-related injury, in the present day we’re going to make a wise gadget that detects the lightning close by and it routinely cuts off the facility, and isolates it electronically with primary energy line inputs.
Right here the relay is used to optically couple the working circuit and electronically isolate the AC circuit and brakes the circuit when the lightning is close by.
The AS3935 Lightning Sensor is able to detecting lightning and offering details about the gap and depth of the lightning, all whereas eliminating the interference attributable to electrical arcs and noise.

Lightning Safety Gadget – Coding
First, we have to set up the library for interfacing the sensor; so open the Arduino library supervisor, seek for the Df robotic lightning sensor, and set up the library.Â
Now embrace the library within the code then set the pins and different configurations within the code.
Now create the loop after which examine the sensor information and get the lightning power and the lightning distance. Now create the if situation to show off the relay and energy of the house when the lightning is close by. you possibly can set any worth that you simply suppose the lightning is close by and may trigger injury. Right here I’ve used the 0.7 km so if the lightning is round 0.7 km away from dwelling it turns off the facility to avoid wasting the home equipment.

Lightning Safety Gadget – Circuit Diagram
Now join the part in keeping with the circuit diagram given under. Right here we related Arduino Nano, Relay, and an AS3935 sensor collectively.
Testing
Now join the parts after which join the Equipment to the relay of the NC pin. Then energy the Arduino and replay with 5V. Now when lightning happens close to the home, it routinely brakes the circuit to guard the equipment from the lightning strike.
That is how one can construct your personal lightning safety gadget. you can too examine the excessive/low voltage safety circuit.
