Description of product


Maker Object is a tiny digital infrared (IR) proximity sensor designed for object/obstacle detection. The IR signal is modulated at 38kHz makes it immune to the ambient light. The Maker Object has NPN output with an internal pull-up resistor. Its output is low when the object is detected. The sensing range is adjustable via the small opening at the front of the sensor. This makes it easily accessible even though the sensor is mounted on the robot.

Due to its small form factor, Maker Object can be easily fitted in tiny robot such as a mini-sumo robot. The 90 degrees pin header is also very handy allowing us to plug in the sensor directly to the PCB or breadboard for quick testing.

Applications: Sumo Robot, Obstacle Avoidance Robot, Auto Gate Safety Sensor, Parking Lot Occupancy Sensor, Entrance Sensor…etc
