Obstacle Avoidance Module Infrared Obstacle Avoidance Sensor Module

Description

Description:

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.
