## Description

The Gravity Lightning Sensor employs AMS's AS3935 lightning sensor IC and a Coilcraft MA5532-AE dedicated antenna to detect lightning distance, intensity, and frequency within a radius of 40km both indoors or outdoors. The embedded interference rejection algorithm can effectively suppress the interference generated by household appliances. In addition to allowing weather enthusiasts to measure local thunderstorm data simply and efficiently, thanks to its compact size and wide detection range, it can also be embedded in various smart wearable devices, like for an outdoor climber or people who work at heights. The sensor can also be embedded in the indoor protection device inside lightning-sensitive equipment, automatically switching these devices to backup power. When lightning is detected the interrupt pin IRQ generates a pulse. This can be used to trigger a cameras shutter to open, helping photographers to accurately capture images of lightning.
