IRF150 --- Infrared Range Finder
Overview
IRF150 is an infrared range finder module consisting of
a GP2Y0A02YK reflective optical sensor module,
which emits infrared light to detect the reflective
infrared intensity and an Analog-to-Pulse (A2P)
Converter board. The A2P Converter board converts the
analog output of GP2Y0A02YK into pulse width. By
measuring the pulse width, the analog readings can be
obtained with the PulseIn command. The analog output
can also be read directly with the command GetADC
command from the I/O Extender module. The
recommended detection range is 20~150cm.
Applications
Short distance range finding
Proximity detection for collision
Contactless switch
