Brightness in CCU 999.99 Lux #35

Closed JocB1 closed 4 years ago

JocB1 commented 4 years ago

Hello, I build the Uni Sens1 Sensor with the newest Asksinpp lib and the newest Addon for the CCU. In the darkness the CCU shows 999.00 Lux - may be an overrun problem... I use the TSL 2561 Sensor (and a BME280). Any Idea?

you probably saw this: https://github.com/TomMajor/SmartHome/tree/master/Info/SensorTest_Lux

I don't use the TSL2561 anymore because of problems in the sunlight, But it should be fine in darkness.

I would suggest to use debug output in the measure loop to check all values what's going on https://github.com/TomMajor/SmartHome/blob/master/HB-UNI-Sensor1/Sensors/Sens_TSL2561.h#L90

Here my debug outputs:

dark: BME280 Temperature x10 : 231 BME280 Pressure x10 : 9715 BME280 PressureNN x10 : 9715 BME280 Humidity : 51 TSL2561 Sensitivity : 0 TSL2561 Brightness Raw Full: 0 !! TSL2561 Brightness Raw IR : 0 !! TSL2561 Brightness Lux x100: 99999 !!!!!! --> CCU: 999.99 Lux

indoor: BME280 Temperature x10 : 220 BME280 Pressure x10 : 9714 BME280 PressureNN x10 : 9714 BME280 Humidity : 55 TSL2561 Sensitivity : 2 TSL2561 Brightness Raw Full: 506 TSL2561 Brightness Raw IR : 80 TSL2561 Brightness Lux x100: 20700 -> CCU: 207 Lux

the overflow detection code for direct sunlight 2 years ago doesn't take zero raw values into account. You could try to extend this first part of the if condition (_brightnessRawFull == _brightnessRawIR) with a logical AND && (_brightnessRawFull != 0) still not perfect for raw values where _brightnessRawFull is equal _brightnessRawIR but have no other idea at the moment.
