Gravity Digital Adjustable Infrared Proximity Sensor

This Gravity infrared proximity switch from DFRobot detects objects in a range of 0 to 200 cm. The switching distance is set with the screw on the back. If an object is within range, the digital output switches to HIGH; the output is PNP, normally open. The cylindrical housing with 18 mm diameter is fixed via its thread in a hole or on a bracket.

Note: Infrared light is also contained in sunlight. The sensor is not suitable outdoors with a lot of sun and reflective surfaces; do not point the optical axis at strong light sources such as the sun or incandescent lamps.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
