Product Introduction

The KH.DC Atmospheric Electric Field Sensor is a high-precision lightning monitoring device designed for continuous measurement of atmospheric electric field changes and lightning risk assessment.

By detecting variations in atmospheric electric field intensity before and during thunderstorms, the sensor provides critical data for lightning warning systems, meteorological observation networks, and outdoor safety monitoring applications.

With RS485 MODBUS communication, the KH.DC can be seamlessly integrated with automatic weather stations, IoT monitoring platforms, telemetry systems, and lightning protection networks. Its rugged aluminum alloy housing provides excellent durability and environmental resistance, enabling reliable long-term deployment in open fields, coastal areas, mountainous regions, and industrial environments.

The KH.DC helps organizations improve lightning risk awareness and enhance safety management for agriculture, infrastructure, and outdoor operations.

How It Works

The KH.DC measures changes in the atmospheric electric field caused by charge accumulation and atmospheric electrical activity.

Before and during thunderstorm development, variations in electric field intensity can indicate increasing lightning risk. The sensor continuously collects electric field data and transmits real-time measurements to monitoring platforms for analysis and warning generation.

This measurement method provides:

• Continuous atmospheric electric field monitoring
• Early indication of thunderstorm activity
• Real-time data transmission for warning systems
• Reliable operation in outdoor environments
