Digital Laser Proximity Sensor 1-400cm IP67

The DFRobot digital laser proximity sensor reports whether an object is within a set distance. The switching distance is adjustable from 1 to 400 cm and is taught without programming using the button on the sensor. The sensor works with diffuse reflection of a 940 nm laser and does not output a distance value, only high or low. The housing of flame-retardant plastic is protected to IP67 and has a thread with nut for mounting.

Note: The sensor runs on 5 to 24 V. With a supply above 5 V, measure the level at the output before connecting it to a microcontroller.

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