[Resource] DigiLTN-Lightning Sensor, SDI12, RS485 Interface

　　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.
