Description
The IR Sensor Module is a versatile infrared-based proximity and obstacle detection module designed for embedded systems and automation applications. It operates by emitting infrared light via the onboard IR LED and detecting reflected signals through the photodiode receiver. When an object enters the detection range, the module outputs a LOW digital signal, making it ideal for real-time obstacle avoidance and object detection logic.
Key Specifications:
- Operating Voltage: 3.3V – 5V DC
- Output Type: Digital (HIGH / LOW)
