industrial sensor with arduino

-

hi :)

i new arduino , happy if me read value of photoelectric sensor. university project planning buy sensor: http://www.produktinfo.conrad.com/datenblaetter/150000-174999/155921-da-01-ml-reflex_lichtschr_sn_2000mm_de_en_fr.pdf
and supply 24v. want read analog signal sensor using analog pin a0. problem analog input pin voltage should limited 5v. thought of voltage divider have no experience it. please take @ attached photo , tell me whether work?

thanks in advance :)

you have drawn sensor 3 wires, red, blue , black. think have exchanged blue , black. according datasheet, blue wire of sensor gnd , black wire output signal.

the arduino gnd must connected sensor gnd.

why use 24v, sensor run fine 12v.

i think sensor outputs digial signal, therefor need digital input.

the 2k2 , 10k okay. may use higher values.
the arduino uno requires @ least 3.0v solid digital high signal.

edit: had calculations voltage divider wrong, removed now.

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp...
