Infrared Obstacle Avoidance IR Sensor Module

• Detection range: 2cm to 30cm
• Detection angle: 35 degrees
• Operating voltage: DC 3.3V to 5V
• Output signal: TTL level

An infrared obstacle avoidance IR sensor module has two infrared sensors that can detect obstacles in front of them. It typically has three pins: VCC (power supply), GND (ground), and OUT (output). The VCC pin provides power to the module, usually 5V. The module has a built-in IR transmitter and receiver that emits IR energy and looks for reflected IR energy to detect obstacles. The output pin gives out a digital signal when it detects an obstacle or reflection. This signal is low-level. The module also has an onboard potentiometer that lets users adjust the detection range. The effective distance range is 2cm to 30cm.
