Description
The Maker Object is a high-precision, miniature digital infrared (IR) proximity sensor engineered for reliable object and obstacle detection in space-constrained robotic environments. By utilizing a 38kHz modulated IR signal, the sensor maintains high immunity to ambient light interference, ensuring consistent performance in diverse operational settings. It features an NPN output with an internal pull-up resistor, providing a clear “active low” signal when an obstacle is detected within its line of sight.
Designed with professional industrial integration in mind, the sensing range of the Maker Object is easily adjustable via a front-facing access point, allowing for rapid field calibration even after the sensor is mounted to a chassis. Its ultra-compact form factor and 90-degree header orientation make it an ideal choice for integration into professional mini-sumo robots, autonomous navigation systems, and compact automation rigs.
