Introduction In the world of embedded systems and robotics, obstacle detection is one of the most fundamental requirements. Among the myriad of sensors available for this task, the FC-51 IR Sensor Module stands out as one of the most popular, affordable, and reliable choices for hobbyists and professionals alike. Whether you are building a line-following robot, a

Note on 4-pin versions: Some FC-51 modules break out an additional pin, which provides the raw analog voltage from the phototransistor before it goes into the comparator. This can be used for measuring distance more precisely. 3. Technical Specifications (Derived from FC-51 Datasheet) The following specifications are typical for the standard FC-51 module. Always check your specific vendor datasheet, but the values below are industry-standard. You can read it reliably at intervals of 10 ms or more

It has a built-in potentiometer to adjust the detection threshold (sensitivity range). 2. FC-51 Sensor Pinout Before diving into the datasheet numbers, let's look at the physical interface. The FC-51 module typically has three pins (although some variants have 4, with an extra analog output pin).

A: Yes. The FC-51 operates from 3.3V to 5V. Connect VCC to 3.3V, and the OUT pin will output 3.3V logic HIGH, safe for 3.3V microcontrollers.
