The Obstacle Avoidance Module comes as an assembled module, as shown above, there are only four pins: 5-volts, GND, output, and EN. Output is an active LOW and has an onboard status LED. The Obstacle Avoidance Module is very easy to interface directly with Arduino or other micro-controllers. Obstacle Avoidance Module also works with the Raspberry Pi with a voltage range of 3-6 volts. Connect Vcc to 3-volts! The enable pin EN will disable the device when HI (Vcc) and enable it when LO (GND). The onboard jumper can be left open to allow external control of enable/disable of the module. I see no use for this function and would leave the jumper on and the pin disconnected. There are two potentiometers on the module one controlling operating frequency (centred at 38 kHz) and the other controlling intensity. Technical Specifications: Working voltage: DC 3.3V – 5V Working current: More than 20mA Working temperature: -10 to 50 centigrade degree Detection distance: 2 – 40cm IO interface : 4 line (- / / S / EN) Output signal: TTL Level Adjusting mode: Multi-resistance regulation Effective angle: 35 degrees The comparator using LM393, is stable. With the screw holes of 3mm, easy to install. Applications: Obstacle Avoidance: In robotics, these modules are often used in obstacle avoidance systems to help robots navigate and avoid collisions with objects. Line Following: In line-following robots, these modules can detect lines on the ground or track and help the robot stay on the desired path. Object Detection: They can be used for general-purpose object detection in various automation and control applications. Package Includes: 1 Piece- Infrared Obstacle Avoidance Sensor Module
