Grove - Lightning Sensor (AS3935)

The Grove AS3935 Lightning sensor is an easy-to-use sensor built around the AS3935 IC, which can detect both cloud-to-ground and intra-cloud types of lightning, for up to 30 or 40 km. It is programmable with I2C or SPI communication and supports 3.3V and 5.0V power supply.

This sensor evaluates the electric fields in the air and verifies the specific characteristic waveform of Lightning, finally sending the output to the development board. It represents a great application of electric field processing, which can be used to create alert systems for Lightning or violent storms approaching and for making complete forecast meteorological stations with adverse conditions alert.

Features

• Lightning Sensor: Detect both cloud-to-ground and intra-cloud types of lightning, based on the electric fields
