5pcs IR Infrared Obstacle Avoidance Sensor Module, Adjustable Detection Range, Easy Assembly and Use for Smart Car Robot, Robot Obstacle Avoidance, Black and White Line Tracking, - ZJchao, ZJchao34csvgzp85

• [Active Infrared Sensor] Detects based on target reflectivity and shape. black objects have shorter range, white objects have longer range. small objects are detected at a shorter distance than large objects. [Versatile Usage] Output port can connect directly to micro-controller io port or drive a 5v relay. suitable for various applications such as smart cars, robots, and assembly lines. [Adjustable Detection Range] The potentiometer allows for easy adjustment, minimal interference, and simple assembly. ideal for robot obstacle avoidance, assembly lines, and black and white line tracking. [Green Indicator Light] Blinking green light obstacles detected ahead. out port outputs low-level . easily adjust detection distance with the potentiometer. [Stable Performance] Comparator uses lm393 chips for stable performance. convenient 3mm screw holes for easy fixation. operates on 3-5v dc power supply., Manufacturer: ZJchao
