Sharp IR Infrared Proximity Sensor – Long Range Detection

The Sharp IR Proximity Sensor uses infrared light reflection technology to detect objects without any physical contact. Its long-range capability allows detection of objects from 10cm up to 80cm or more (depending on model), making it suitable for robotics, obstacle avoidance, automation, and industrial sensing applications.

The sensor outputs an analog voltage proportional to the detected distance, which makes it compatible with Arduino, NodeMcu, ESP32, Raspberry Pi (with ADC), and other microcontrollers. This enables precise distance measurement for navigation, smart robotics, home automation, and IoT-based object monitoring.
