Automatic Street lighting Dimming by illuminance Lux Sensor

Detailed of the PLC & LoRa Technology showing on 93km Shen Zhen Outer Ring Expressway Street Lights & Tunnel Light Groups:

Illuminance Sensor(Lux Sensor)

I: Equipment Introduction

CH C208 illuminance Sensor(Lux Sensor) is independently researched and developed by our company. According to the Roads ambient conditions, it cooperates with the intelligent lighting centralized controller to automatically control the illuminance of the lamps according to the changing of environmental brightness, to achieve the purpose of intelligent led street lighting management.

Traditional municipal street lighting, tunnel lighting, industrial lighting such as factory&warehouse lighting Switches Controlling Modes are generally divided into Loop Controlling, Sunrise & Sunset Controlling, the corresponding fixtures Loop Controlling in different time periods. Although the controlling is mature and widely used, there are still many problems, such as: it can’t be automatically adjusted Brightness at rainy, sandy weather , the adjustment range is fixed (only loop switch); moreover, it is impossible to know the environmental brightness of the project site in time. In response to these problems, our company launched this Luminance Collection Equipment. which integrates brightness collection, data processing, and data communication.

The device adopts GPRS/4G communication mode, which can report the collected brightness data to the server directly.

III: Key Functions

1. Brightness Collection Function

Using industrial high-precision photoelectric sensor, complete set of lens, filter, aperture and other devices, to collect the environment reflected light, through the internal high-speed data calculation unit, according to the algorithm for data conversion, using a unique fault-tolerant mechanism to ensure smooth and effective data, to ensure accurate and effective acquisition of optical brightness.

2. Communication Function

Using GPRS channel for data transmission, data interaction and parameter configuration operations can be carried out with the server.

It can be set as Active Reporting or Polling communication type.
