The OSEPP IR Proximity Sensor Module measures distances. It utilizes the Sharp GP2Y0D805Z0F measuring sensor unit which is composed of an integrated combination of photo diode, infrared emitting diode and a signal processor. The digital value from the proximity sensor is read out on the I²C bus. The module uses the I²C interface for data communication.
In a Proximity Sensor an IR LED and a Photodiode is used to find a obstacles . The IR LED transmits light in forward direction when an obstacle is ahead the light reflects and the Photodiode is activated by this method Obstacle is detected. There are many IR modules available online which are cheap they cost about ₹200 or about $2-3 . Sharp IR Distance Sensor (GP2Y0A21YK0F) Measurement range: 10cm to 80cm (3.9" to 31.5") The Sharp GP2Y0A21YK0F infrared distance measuring sensor uses a beam of infrared light to reflect off an object to measure its distance. Because it uses triangulation of the beam of light to calculate the distance, it is able to provide consistent and reliable readings which are less sensitive to temperature variation or the object's reflectivity.
