Infrared Obstacle Avoidance IR Sensor Module adaptable to ambient light, having a pair of infrared emitting and receiving tubes, transmitting tubes emit infrared certain frequency, when the direction of an obstacle is detected The module features a 3 wire interface with Vcc, GND and an OUTPUT pin on its tail. It works fine with 3.3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine-tune the range of operation, the effective distance range is 2cm to 80cm. – Onboard LED indicates if the module is connected properly – Another onboard LED indicates when threshold values are touched (turns on) – Great for DIY projects and Arduino beginners – M3 Mounting holes to mount the module on your desk or project – Proximity range up to 7 centimeters depending on the obstructing object and surrounding environment. Specifications: Detection range: 2 ~ 80cm Detection angle: 35 ° 3mm screw holes for easy mounting Package Includes : 1 x Infrared Obstacle Avoidance IR Sensor Module
