The is a widely used, affordable sensor designed for detecting the presence of objects in close proximity. Primarily used in robotics for obstacle avoidance and in automation systems for proximity detection, the FC-51 operates by emitting infrared light and measuring the reflected light.
If you are building a line-following robot, a tachometer, or a proximity alarm, chances are you’ve stumbled upon the . It is one of the most ubiquitous, low-cost infrared obstacle avoidance sensors on the market.

If the reflection is strong enough (meaning an object is close), the module drives its digital output pin ( OUT ) LOW (0V) and illuminates the onboard obstacle indicator LED. If no obstacle is present, the output remains HIGH (VCC) . 2. Technical Specifications Specification Value Operating Voltage (VCC) 3.3V to 5V DC Operating Current ≥is greater than or equal to Output Type
