Hi Guys,
So I'm in the middle of a project using this:
https://www.amazon.co.uk/Photoelectric-Switch-Sensor-Module-50mmx25mm/dp/B00BLZ93T2/ref=pd_sim_sbs_201_2?ie=UTF8&dpID=41J7toU-nQL&dpSrc=sims&preST=_AC_UL160_SR160,160_&refRID=04WC388RPP0QZKMPT3JK
But i have come to build the final system and they have all sold out and alternative sellers will arrive to late. So I need to either find someone who can deliver by Friday or I need an equivalent device i can search for.
Has anyone used anything similar they could recommend?
Thank you for you help in advance.
