RS485 Waterproof Ambient Light Sensor measures 0 to 200,000 lx using Modbus RTU. Its IP68 enclosure and 5 to 32 V DC supply support indoor and outdoor light monitoring. More product details

Product Description

RS485 Waterproof Ambient Light Sensor SEN0644 from DFRobot measures illuminance in indoor and outdoor environments. It is intended for integration into weather stations, greenhouse controls and lighting systems that respond to ambient light. The IP68 enclosure supports use in wet or humid surroundings, including submersion. Measurements are transmitted through RS485 using Modbus RTU. Connection to Arduino and other microcontroller platforms uses a suitable interface adapter, while an external 5 to 32 V DC source supplies power.

Highlights

IP68 waterproof enclosure suitable for submersion.
Measurement range of 0 to 200,000 lx covers dim indoor conditions and bright outdoor light.
Resolution of 0.01 lx for illuminance measurement.
Measurement accuracy of ±5% for light monitoring and lighting control.
Modbus RTU communication over RS485 supports microcontroller integration through suitable adapters.

Technical Features

Measurement range: 0 to 200,000 lx.
Resolution: 0.01 lx; measurement accuracy: ±5%.
Interface and protocol: RS485, Modbus RTU.
Supply voltage: 5 to 32 V DC.
Operating current: less than 10 mA.
Operating temperature: −40 to +80 °C.
Protection rating: IP68.
Cable length: 1 m.
Cable diameter: 4 to 10 mm.
Opening size: 25 mm.
Thread length: 10 mm.
Wrench size: 33 mm.

Application Areas

Weather stations record ambient light as part of their weather data.
Greenhouse controls monitor lighting conditions during vegetable and flower cultivation.
Streetlights and garden lighting switch according to measured ambient light levels.
Adaptive vehicle lighting uses ambient light measurements to adjust illumination.
Factory lighting systems monitor illuminance in industrial workshops.

Notes

Arduino and other microcontrollers require a suitable RS485 connection, for example through a TTL-to-RS485 adapter.
The external DC power supply must remain within the 5 to 32 V range.
