Product Details
Infrared (IR) break-beam sensors offer an easy way to detect motion. The emitter sends out an invisible IR light beam, and the receiver on the other side is sensitive to it. When an opaque object passes between them, the beam is broken, and the receiver outputs a signal. This IR break beam sensor has a 4m sensing range and a super-fast, stable 0.5 ms response. Its compact size allows for convenient installation in tight spaces. It can work in temperatures from -10°C to 60°C. Powered by a 5V DC voltage, it's great for use with Arduino in smart robot competitions for tasks like simple motion detection, speed detection, and timing. Key features include a 4m detection range, small size, and fast response. It's suitable for simple motion detection, speed detection, and timing. Specifications are as follows: Operating Voltage is DC 5V, Output Current is 30mA, Output Power is 100mW, Sensing Range is 4m, Sensing Mode is thru-beam for non-transparent objects, Wavelength is 830nm, Emitting Angle is a straight line of infrared light, Receiving Angle is ±5°, Response Time is 0.5ms, Operating Temperature ranges from -10 to +60°C, Storage Temperature ranges from -20 to +80°C. The transmitter has a red wire for 5V, a black wire for GND, and a green wire that's floating, while the receiver has a red wire for 5V, a black wire for GND, and a blue wire that's floating. The transmitter has a green PCB, and the receiver has a black PCB. The shipping list includes one 5V IR Photoelectric Switch (4m).
Using this 5V IR Photoelectric Switch is quite straightforward. First, connect the wires correctly according to the specifications. The red wire is for 5V, the black wire is for GND, and the floating wires (green for the transmitter and blue for the receiver) are for signal output. Place the emitter and receiver facing each other with a clear line of sight, and make sure the distance between them is within the 4m sensing range. When an object passes between them, the switch will detect the motion. For best results, avoid placing the sensor in areas with direct sunlight or strong infrared interference. Keep the sensor clean and free from dust. If you're using it in a robot competition with Arduino, make sure the Arduino is properly programmed to handle the signals from the sensor. When not in use, store the sensor in a dry place with a temperature between -20°C and 80°C.
