Floricx IR Sensor Module with LM393 10-38kHz Adjustable Frequency Pack of 5 IR Sensors

An IR sensor module is a device that detects objects or changes in the environment using infrared light. IR light is invisible to the human eye, but it can be detected by special sensors. IR sensor modules are commonly used in robotics, automation, and consumer electronics. An IR sensor module typically consists of two main components: IR LED transmitter: This component emits infrared light beams. IR photodiode receiver: This component detects infrared light beams. The IR sensor module works by emitting infrared light beams and then detecting whether any of those beams are reflected back to the receiver. If a beam is reflected back, it means that an object is blocking the beam. The module can then use this information to determine the presence, distance, or motion of the object. IR sensor modules are relatively inexpensive and easy to use. They are also very reliable and have a long lifespan.
