This photo shows the upgraded sensor boards as fitted into APBs. The boards can be used with the APB, as here, or the ARC PRO. When used for the latter, a few additional components are added to enable IR blade detection. These were assembled a year ago and then dispatched to SSD users in the USA.

   

This photo shows a similar four-phototransistor design designed for single lane use or where lane pitch is non-standard. This of course corresponds to pit lanes or more generally for routed tracks. These types of sensors have been in use for a couple of years and build on a prototype design which was first tested back in 2019. All user feedback to date has been highly positive.

Used as pit sensors the boards can interface directly onto Arduino digital input pins so great for DIY-ers too.
