Yesterday I accidently switch the GND and VCC part of this sensor ISO203 from this laser sensor, and now whenever I point the laser at the sensor it doesnt change the state of the output. Is my sensor really dead?
Laser sensor is a misnomer (advertising bull).
I would just call it "light sensor".
What kind of light do you use.
The sensor seems to peak at 900nm (infrared).

Maybe try it with sunlight.
Do you get a constant HIGH or a constant LOW.
Post a picture of the build and the code.
Maybe we can spot something before you replace the sensor.
