Overview
The Milesight EM500-LGT LoRaWAN Light Sensor is a professional-grade device designed for accurate ambient light measurement in outdoor and industrial environments. It uses advanced photodiode technology to detect light intensity from 0 to 100,000 lux. This wide range allows it to function in low-light agricultural areas, bright urban settings, and industrial applications. In addition, the sensor provides a fast 1-second response, enabling real-time monitoring for automated lighting control, crop growth tracking, energy management, and other time-sensitive applications.
Rugged and Long-Lasting Design
The EM500-LGT is built for durability. Its IP67-rated enclosure protects it from dust, rain, and harsh weather, allowing reliable operation even in extreme outdoor conditions. Moreover, the sensor features a rugged housing that ensures consistent performance over years. It is powered by a 19,000 mAh replaceable battery capable of lasting up to 10 years. This long-lasting power, combined with low energy consumption, reduces maintenance needs. Therefore, it is ideal for remote areas where frequent servicing is difficult.
Connectivity and Remote Monitoring
The sensor connects via LoRaWAN®, enabling seamless integration into IoT networks. This allows centralized monitoring, remote configuration, and efficient data collection. In addition, the EM500-LGT detects subtle changes in light intensity. As a result, it can optimize lighting schedules, improve plant growth efficiency, reduce energy waste, and enhance urban safety.
Versatile Applications
The EM500-LGT is suitable for many environments. In smart agriculture, it monitors sunlight exposure, optimizes crop lighting, and supports plant growth studies. In urban infrastructure, it enables intelligent street lighting, energy efficiency, and environmental monitoring. Industrial sites can use it to ensure proper illumination for safe operations. It also serves research and environmental studies that require precise, long-term light measurement. Its combination of durability, connectivity, high accuracy, and low maintenance makes it an ideal solution for professional outdoor and industrial light monitoring.
