Infrared Barrier Range Finder Obstacles Module for Arduino SN-IRB-MOD

The Infrared Barrier Module is able to adapt to the environment light very well. Having a pair of infrared transmitter and receiver tube, the transmitter consistently emits a certain frequency. When an obstacle with reflective surface is encountered, the infrared reflected back is received by the receiver & sent to the comparator circuit for processing. The green light will lit and output digital signal (low). The detection range can be adjusted via the potentiometer knob

Features:

• Adapt to light very well
• Green indicator will light and output digital signal (low) if there is obstacle
• Checking effective range is 2~30cm (depends on object reflectivity)
• Working voltage: 3.3~5V
• Easy to install and convenient to use
• Application: Widely used in robot, small car, obstacle avoidance trolley, assembly line count, and black and white line tracking, etc.
• Output port can connect to IO port directly or can drive 5V relay
• Connecting mode: VCC-VCC, GND-GND,OUT-IO
• Comparator adopts LM393, stable
• Red power indicator
• Comes with 3mm screw hole
• Dimensions: 4.7 cm x 1.9 cm x 0.8 cm
• Weight: 1.66 oz (47 g)
