DFRobot Gravity – Lightning Sensor

The module is equipped with theAMS AS3935 Franklinsystem and a special antennaCoilcraft MA5532-AEfor determining thedistancefrom atmospheric discharges,intensityandfrequencywithin40 kminside or outside. The kit includes a cable adapted to Gravity DFRobot IO Expansion Shield.

Dueto the small dimensionsandwide detection range, it can also be used insmart clothingfor individuals working at heights. The sensor can also be used inintelligent building, which, after detecting the near atmospheric discharges, it gives the command of disconnecting from the electricity, the sensitive to these effects, devices. The module can also be useful for photographers at the moment of detection of the lightning,pin IRG generating the impulsecan be used to open the shutter.
