　　DigiLTN is an advisory instrument used for the detection of lightning strikes. The sensor indiscriminately detects cloud-to-cloud, intra-cloud, and cloud-to-ground discharges. It provides strike count, estimated distance of the last strike (0 to 40 km/24 miles), and several other parameters through the RS485 or SDI-12 interface. The SDI-12 output provides universal compatibility with any SDI-12-enabled data logger and low power applications, or use a RS485 physical interface for applications that require long cable runs or many sensors.

Specification
Output Interface	Optional: SDI-12, V1.3 Optional: RS485, Modbus-RTU
Power Supply	5-28V DC
Power Consumption	SDI-12 Interface: Quiescent current: <400uA @12V DC Max. current during lightning detected: <5mA @12V DC RS485 Interface: Quiescent current: <1.2mA @12V DC Max. current during lightning detected: <6mA @12V DC
Detection	Storm head Range Estimate: 15 values from 0 km to 40 km (0 miles to 24 miles) Consecutive Strike Span: 1 s Detection Efficiency: Approximately 40% Detection efficiency is dependent on the use environment and the level of ambient, man-made electromagnetic noise. Detection thresholds are user configurable and may be increased to reduce the false detection rate at industrial environments, but this will also impact lightning detection.
