: Digital signal (High/Low). It outputs a LOW signal when an obstacle is detected.
The FC-51 IR sensor datasheet had provided him with the necessary information to get started. He noted that the sensor operated at a voltage of 3.3V to 5V, with a maximum current consumption of 20mA. The datasheet also mentioned that the sensor's infrared LED emitted light at a wavelength of 950nm, which was perfect for detecting obstacles. fc 51 ir sensor datasheet hot
: Features an IR transmitter (LED), an IR receiver (photodiode), and an LM393 voltage comparator for stable digital switching. Pinout and Connectivity : Digital signal (High/Low)
