1000 PCS 3mm 940nm IR Transmitter

The 3-millimeter infrared transmitter is one of the most widely used components in the design of electronic systems and robotics projects, which, by emitting infrared light at a wavelength of about 940 nanometers, provides the possibility of sending an optical signal to infrared receivers. With a body diameter of 3 millimeters and a transparent or semi-dark design, this infrared transmitter is considered a suitable option for compact circuits and obstacle detection modules. Low energy consumption, fast response, and a suitable emission angle are among the features that have made this 3-millimeter infrared diode very popular in applications such as remote control systems, distance sensors, optical counters, and Arduino projects. Using this sensor alongside an infrared receiver tuned to the same wavelength significantly increases performance accuracy. To protect the diode and prevent it from being damaged by high current, using a current-limiting resistor in the circuit is essential.

This component is compatible with all microcontroller platforms such as Arduino, ESP32, AVR, and STM32, and it is also widely used in the design of Internet of Things-based systems. Among the other important applications of this component is its use as an infrared obstacle detection sensor, which is common in robotics and industrial automation projects.
