Oumefar 5pcs IR Infrared Obstacle Avoidance Sensor Module Barrier for Smart Car Robot

Wide applications: This 5-piece IR infrared obstacle avoidance sensor module can be widely used to avoid obstacles of robots, cars to avoid obstacles, assembly lines, black and black lines and many other occasions Multiple working method: The output port of the IR infrared obstacle avoidance sensor module can be directly connected to the IO port of the microcontroller, which can also drive 5V forunrelay directly Low negative impact: The detection range of this photoelectric IR obstacle avoidance sensor can be adjusted with a forunpotentiometer, which has little interference, and this avoidance sensor module is easy to assemble Adjustable function: when the signal module detects obstacles forward, the green indicator light on the circuit board is turned on and at the same time the output port emits a low-level signal; the detection distance can be adjusted with a potentiometer, clockwise to increase the detection distance Note: active infrared reflection detection sensor, so the reflectivity and the shape of the objective are the key to the detection range. The black colour has the minimum detection range, the maximum detection range, small objects have a short detection range, large objects have a long detection range
