Fc 51 Ir Sensor Datasheet [2021] 〈360p 2024〉

The official FC-51 datasheet is sparse (often just a pinout and a schematic). Here’s the .

Unlike passive infrared (PIR) sensors, which detect heat emitted by humans or animals, the FC-51 is an active sensor. It acts as a sonar system using light rather than sound. It consists of an IR transmitter (LED) and an IR receiver (photodiode or phototransistor) mounted side-by-side on a small PCB. Fc 51 Ir Sensor Datasheet
