The sensor can detect lightning discharges both from the cloud to the ground and inside the cloud, within a radius of up to 40 km.

Special features of the sensor

  • High sensitivity: the sensor reacts to even small electric fields in the air, so it is able to quickly detect an approaching thunderstorm front.
  • Advanced algorithm: uses an internal algorithm to identify characteristic electrical waves, allowing you to accurately determine the presence of a storm.
  • Simple operation: thanks to the I2C communication interface and Grove connector, the sensor is easy to use and can be quickly integrated into various development boards.
  • Low Power Consumption: Has a sleep mode function that helps reduce power consumption and extend the life of batteries or other power sources.
  • High Performance: With a maximum detection range of up to 40 km, the sensor can effectively warn of approaching storms, ensuring the safety of both people and electrical equipment.

How does a lightning sensor work?

The sensor's operation is based on the assessment of electric fields in the air and verification of the specific shape of electric waves typical of thunderstorm fronts , which allows for precise detection of lightning discharges. This sensor is extremely sensitive and reacts even to small changes in the electric field, which allows for quick detection of threats and taking appropriate precautions. Additionally, as part of the Grove ecosystem, the sensor is easy to connect and use, making it ideal for users who are just getting started with electronics. The sensor allows you to create a variety of applications , such as forecasting alerts about approaching thunderstorms, weather stations , or automated security systems that prevent damage to electrical equipment. It is an indispensable tool for everyone who is interested in monitoring weather and atmospheric phenomena, both at home and in the workplace.
