Modulated Infrared Reflective Detector - #3-337
Section 1 - Introduction
This kit detects objects by means of a modulated
(flashing) beam of infrared light. Its output signal can sink
up to 100 mA for direct drive of an LED indicator, a relay,
or as an input to a microprocessor. It makes an ideal
proximity detector for miniature robots. Use it wherever you
require non-contact object detection at close range with high
noise immunity!
Size: 18 x 21 x 9 mm thick (0.75 x 0.88 x 0.38 in.)
Weight: less than 3.4 grams
Voltage: 5.0 V nominal input
Output: open collector, sinks up to 100 mA
Range: to 8 cm (3 in.) depends on target reflectivity
High Noise Immunity: modulated beam reduces
response to ambient infrared signals
Easily assembled in under an hour - soldering
required. Electronics experience helpful but not required.
In addition, assembly and operation will require:
1. Fine tip soldering iron for electronics
2. Solder for electronics
3. Moist sponge to clean soldering iron tip
4. Wire stripper Top view with components in place (enlarged)
5. Side cutter
6. 5 Volt DC power source
