IRPS
Infra Red reflective proximity sensor
This simple IR proximity sensor uses 'modulated
burst' sensing method to avoid false triggering
and interference.
It has a range of about 4 -12cm (depending on the
type of reflective surface), and will not respond at
all to matt black. Response time is around 10mS,
and a small amount of hysteresis (about 1cm) is
included to avoid 'chattering' at limit range
Vertical and horizontal axis of 'sight' versions will
be available.
