Light Intensity Sensor EM500-LGT – Milesight (LoRaWAN)

The Milesight EM500-LGT measures ambient light intensity in lux for deployments where brightness data drives real actions: switching lights, managing shading, detecting failures, or documenting growing conditions. With a fast 1-second response, it can capture quick changes caused by clouds, shadows, or artificial lighting.

LoRaWAN (EU868) plus battery operation makes it a strong fit for distributed outdoor installations where power and network wiring are impractical. The enclosure is designed for harsh environments: the transceiver is IP67-rated and the light sensor is IP65-rated. A 3 m cable helps place the sensor where it measures correctly while keeping the wireless module in a protected mounting position.

Concrete real-world examples:

Greenhouses and crop production: track light profiles to support shading and supplemental lighting decisions.

Street/parking lighting: use lux thresholds for dusk/dawn control and validate schedules against real brightness.

Security perimeters: detect abnormal light changes (e.g., lighting outages, unexpected illumination).

Industrial yards and logistics areas: trend lighting performance and support maintenance planning.

Smart city / infrastructure: collect brightness data to optimize lighting strategies and energy use.

For reliability in real networks, the device supports on-device storage (1,000 entries), retransmission, and data retrieval, plus threshold alarms. Configuration is quick via NFC, or via USB Type-C and downlink. Mounting options include pole, wall, or DIN rail.
