These sensors appear to be in working order. They'd should be safe to use below child-head height. They were manufactured in 1996 and use a [http://en.wikipedia.org/wiki/Laser_safety#Class_II Class II] laser rated at 3mW with a wavelength of 655-670nm ([[Media:Banner-q45bb6ll.pdf|datasheet]]). The model number is: Q45BB6LL | These sensors appear to be in working order. They'd should be safe to use below child-head height. They were manufactured in 1996 and use a [http://en.wikipedia.org/wiki/Laser_safety#Class_II Class II] laser rated at 3mW (peak), 2kHz 2% duty cycle, with a wavelength of 655-670nm ([[Media:Banner-q45bb6ll.pdf|datasheet]]).

A good signal can be obtained at 1.5m by using a reflector made of aluminium tape. | A good signal can be obtained at 1.5m by using a reflector made of aluminium tape. | ||

The code is available on [https://github.com/londonhackspace/spacensus GitHub] - please be kind it's my first Arduino project and I know the code is filth. | The code is available on [https://github.com/londonhackspace/spacensus GitHub] - please be kind it's my first Arduino project and I know the code is filth. | ||

Spacensus still miscounts - especially when the door is opened for an incoming guest. I am aware of a few issues in the code where detection could be improved so will try a couple of modifications and see how it goes. | Spacensus still miscounts - especially when the door is opened for an incoming guest.
