IR Proximity Sensor

The IR Proximity Sensor module has great adaptive capability of the ambient light, having a pair of infrared transmitter and the receiver tube, the infrared emitting tube to emit a certain frequency, encounters an obstacle detection direction (reflecting surface), infrared reflected back to the receiver tube receiving, after a comparator circuit processing, the green LED lights up, while the signal output will output digital signal (a low-level signal), through the potentiometer knob to adjust the detection distance, the effective distance range 2 ~ 30cm working voltage of 3.3V-5V.

The detection range of the infrared proximity sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used for line follower robot ,obstacle avoidance, DIY Automatic Sanitizer Dispenser Kit, obstacle avoidance car assembly line count and black-and-white line tracking, and many other occasions.

Features:

• Easy to assemble and use
• Onboard detection indication
• The effective distance range of 2cm to 30cm
• A preset knob to fine-tune distance range
• If there is an obstacle, the indicator lights on the circuit board.

Applications:

• IP cameras
• Alarm systems and other crime prevention devices
• Battery-driven human presence sensors for IoT smart homes
• IR sensors are also used in IR imaging devices, optical power meters, sorting devices, remote sensing, flame monitors, moisture analyzers, night vision devices, infrared astronomy, etc.
