EM500-LGT — Outdoor Light Intensity Monitoring
Milesight EM500-LGT is a wireless sensor designed for continuous light intensity monitoring in outdoor installations and demanding environmental conditions.
The measurement range from 0 to 100 000 lx enables monitoring of both very low light levels and strong daylight. Data is transmitted via the LoRaWAN network to a supervisory system, allowing measurements to be collected from multiple distributed locations.
Precise Light Measurement in Demanding Conditions
0–100 000 lx
The wide measurement range enables observation of changes in light intensity in a variety of outdoor applications.
Fast Response
The sensor responds to changes in light intensity in approximately 1 second, enabling rapid detection of changing conditions.
Outdoor Operation
The IP67 communication module and IP65 light probe enable the device to be used in outdoor measurement installations.
Where Can the EM500-LGT Be Used?
Key Measurement Parameters
Light Data as Part of Automation
Light intensity measurement makes it possible to observe actual lighting conditions instead of basing system operation solely on time schedules.
Data from the EM500-LGT can be used, among other purposes, for lighting control, analysis of plant growth conditions and monitoring light availability at different times of the day and year.
Light Monitoring in Crops
Growth Conditions
Continuous light intensity measurement helps observe how lighting conditions available to plants change throughout the day.
Measurement History
Data collected over time enables comparison of lighting conditions between locations, periods and different parts of a crop.
Distributed Points
LoRaWAN allows sensors to be deployed over a larger area without the need for wired communication infrastructure.
Separate Probe Designed for Outdoor Operation
IP67 Module
The communication unit enclosure protects the electronics against dust and water during operation in outdoor installations.
IP65 Sensor
The separate light intensity probe is designed for operation in changing weather conditions.
3 m Cable
The probe is connected to the transmitter by a 3-metre cable, allowing it to be positioned at the optimal measurement location.
Local Storage and Alarming
1000 Records
The EM500-LGT can locally store up to 1000 historical measurement records.
Retransmission
Stored data can be retransmitted after communication is restored, reducing the risk of gaps in measurement history.
Threshold Alarms
The device allows threshold values to be defined, enabling the system to respond when the light intensity level is too low or too high.
Communication, Power Supply and Design
* The manufacturer declares up to 10 years of operation with a 10-minute reporting interval and a temperature of 25°C. Actual battery life depends on configuration, connection quality and environmental conditions.
EM500-LGT in a Monitoring System
Light intensity data can be transmitted via LoRaWAN to a gateway and then to a supervisory platform. This enables central monitoring of multiple measurement points, analysis of history and generation of alarms based on specified lighting levels.
