Proximity & Distance
Proximity and distance sensors for every project — ultrasonic, IR, LiDAR, ToF, and capacitive types, all stocked in Australia. Whether you're building a robot, an obstacle-avoidance system, or a smart home trigger, you'll find the right sensor here.
Popular with makers, students, and engineers alike, these sensors suit Arduino, Raspberry Pi, and microcontroller projects at any skill level. From short-range gesture detection to 50m laser ranging, there's a solution for hobbyist, STEM, and professional applications.
5V IR Photoelectric Switch (4m)
