The Mini Infrared Emitter & Receiver Unit is a compact photoelectric sensor that brings infrared communication capabilities to your electronics projects. This integrated unit combines both an infrared transmitter operating at 940nm wavelength and a receiver in one convenient package, making it ideal for short-range wireless communication applications. With an effective range of up to 16 feet, this unit excels at infrared encoding and decoding tasks. The compact design measures just 1.26 x 0.94 x 0.31 inches and weighs only 0.16 ounces, making it easy to integrate into space-constrained projects. It connects seamlessly via the HY2.0-4P interface and is compatible with popular development platforms including Arduino, UIFlow with Blockly, and Python. The unit features 2 LEGO-compatible mounting holes for versatile installation options. Perfect for creating infrared remote controls, proximity sensors, or communication systems, this unit leverages the same reliable technology found in household appliances and consumer electronics. Whether you're building a custom remote control, developing a line-following robot, or experimenting with wireless data transmission, this infrared unit provides a straightforward solution for your maker projects.
