Digital Light Sensor LS-03 for brightness measurement. Applications range from simple brightness measurement in rooms to sophisticated museums and galleries. In these objects, the brightness can be measured exactly at their position (e.g. next to a painting on the wall) to protect exhibits and the light intensity in the room can be maintained according to specifications.
It is also possible to record measured values (in conjunction with IPMS visualization). The measured spectrum corresponds to the standardized V-lambda curve (λ) in lux. The sensor can be individually adapted to the conditions on site by extensive parameter settings. Transmission to the Master is done with 1 to 4 digital 8/16 bit values. Due to its small dimensions, the LS-03 can be placed very unobtrusively.

8-pole DIP switch for setting the ISYGLT BUS address (0-127) is located on the rear of the module.
| LED | Designation | State | Meaning |
|---|---|---|---|
| red | Power | Off | No operating voltage |
| On | Operating voltage, no error | ||
| yellow | BUS | Off | BUS wiring error |
| On | Error BUS communication (address) | ||

The function indicators are intended for commissioning and service purposes and should be switched off by parameter during regular operation. Deactivation takes place via the parameters in the ProgramDesigner.
In the ISYGLT ProgramDesigner you will find the parameterisation options:
| Ub | Operating voltage | RJ10 Pin 4 (green) |
| 0V | Operating voltage | RJ10 Pin 3 (brown) |
| A | Subnet (BUS A, RS-485) | RJ10 Pin 2 (white) |
| B | Subnet (BUS B, RS-485) | RJ10 Pin 1 (yellow) |
