Hi
I already own several Rotary Laser Levels which provide a red beam. Their wavelengths range from 630nm and up.
https://en.wikipedia.org/wiki/Laser_level
I want to design and make my own laser receiver/detector. I already own several Rotary Laser Levels which provide a red beam.
I also own several receivers one of which I would like to copy. The receivers signal whether the receiver is higher or lower than the beam with a buzzer and an LCD display. Some receivers only signal whether it is high or low and some signal how high or low it is.
My goal is to build a receiver that tells an Arduino how high or low it is and then control a motor. I don't need the buzzer or LCD screen output and I cannot use the receivers I have.
I have been researching this for a while and have found a bit of info but I am still a little uncertain.
Additional info:
Attached are images of the PCB for the receiver I wish to copy.
I would like to know...
1. Are the sensors in the image photodiodes? (Or possibly phototransistors or photoresistors)
2. As I haven't been able to find the components in the image would any of the following linked components do the same job?
3. Any suggestions as to circuit design, other components (eg. resistors, micro-controller) and programming I should use.
Possible Component Candidates:
Any help would be greatly appreciated
Thanks in advance.

Additional info:
- Just about every forum I have read said that an optical filter would be needed. My receiver has a red transparent filter on it but when I took the receiver apart and tried it without the filter it would still only be triggered by the laser beam.
- I tested across the component of interest when it was turned on but not detecting and it read 3.3v. Not sure if that is helpful.
- The receivers I have can detect the laser in daylight from 100-200 meters plus.
