Manuel Garbe and Drone both wrote in to draw our attention to this new “Lightning Detector” chip from Austriamicrosystems. According to the manufacturer’s press release, “[t]he AS3935 is a programmable Lightning Sensor IC that detects the presence and approach of potentially hazardous lightning activity in the vicinity. It detects intra-cloud activity as well as cloud to ground flashes, often enabling risk to be evaluated for approaching storms, while rejecting interference signals from common man-made sources such as: fluorescent lighting, motors, microwave oven, switches, etc. The flexible IC allows for configurability that allows the part to work both indoors as well as outdoors, just changing the gain setting in a register.”
