Overview
The BTD-1 is a standalone thunderstorm warning system designed to detect the presence and range of lightning flashes by monitoring the background quasi-electrostatic field. In addition to lightning detection, it provides early warning of overhead thunderstorm conditions and includes a Severe Storm feature to identify storm cells most likely to generate damaging events such as large hailstones.
The BTD-1 is ideal for safety-critical outdoor applications, including renewable energy sites, airports, industrial plants, marine and harbour facilities, outdoor sports venues, and construction sites.
With its plug-and-play architecture, optional modules, and integration-ready communication interface, it offers a flexible solution for both standalone deployment and complete warning systems.
- Advanced warning
Provides warning of overhead thunderstorm conditions before the first nearby lightning strike. - Severe Storm feature
Identifies highly active storm cells associated with increased risk of large hailstones and damaging weather. - Best-in-class detection efficiency
High sensitivity to lightning activity, including strong detection of intra-cloud flashes, for earlier and more reliable storm warning. - Unique lightning detection
Low-frequency analysis of thunderstorm activity ensures high detection efficiency with minimal susceptibility to man-made interference. - Long detection range
Measures lightning activity up to 35 km as standard, extendable up to 83 km. - Plug-and-play architecture
M12 connectors, preassembled leads, and modular accessories simplify installation and deployment. - System integration ready
ASCII communication interface for systems integrators, with broadcast messaging, relays, and optional expansion modules. - Low maintenance outdoor design
Robust construction with IP66 protection and no moving parts.

Technical Description
BTD-1 Thunderstorm Detector
The BTD-1 is a standalone thunderstorm warning system designed to detect the presence and range of lightning flashes by monitoring the background quasi-electrostatic field.
Lightning and storm event detection
The BTD-1 detects cloud-to-ground, intra-cloud, and cloud-to-cloud lightning, and also identifies charged precipitation, strong electric field, and severe storm conditions.
Configurable risk management
Four risk levels, All-Clear, Caution, Warning, and Alert, can be configured according to site-specific requirements.
Accurate timing and optional direction
An integrated GPS/GNSS module supports accurate flash timing. With the optional Direction Finder, the system can also provide lightning bearing.
Communications and software
The sensor operates over RS422 with broadcast output every 2 seconds, supports three internal relays, and integrates with the Lightning Eye software environment for monitoring, diagnostics, and data handling.
