Infrared obstacle sensor. Reflective optocoupler for obstacle detection with a shiny reflecting surface. Adjustable sensitivity for a distance of 2–30 cm (set with a potentiometer - you set the distance below which the module outputs a high signal). The sensor has one infrared diode for the transmitter and one for the receiver. If there is an obstacle in the detection area, the green indicator lights up. The sensor has a digital output signal, when there is no obstacle the state on the pin is low 0V and when an obstacle occurs, the state on the pin is high 5V.
Technical parameters:
- IR optical infrared sensor FC-51 - supply voltage: 3.3-5V - transmitting and receiving IR diodes - detection angle 35 ° - response time: 0.5 s - adjustable sensitivity by potentiometer - LED indication of power supply and active status - digital output eg for relay control - size: 32 × 14 mm
The product is not a stand-alone unit, it requires professional installation.
