From 3.3 to 5V, it functions perfectly. The output pin emits a low-level digital signal in response to reflection or obstruction.
Infrared light is not visible to humans, but it is nevertheless useful. For instance, a TV remote control changes the channels by using infrared light. Its presence can be found with a digital camera. When you aim a remote at a smartphone camera and hit a button, the screen of your camera may light up.
Passive and active are the two varieties of infrared sensors. Active infrared sensors are capable of both emitting and detecting infrared light. A light emitting diode (LED) and a receiver make up an active infrared sensor.
A radio transmitter, radio receiver, and tiny radio transponder make up an RFID system. The RFID tag communicates digital data, often an inventory number, back to the reader upon receiving an electromagnetic interrogation pulse from a nearby RFID reader device.
Because they are practical and affordable, infrared (IR) sensors are frequently employed to measure distance. The reflectance amplitude of infrared light emitted by a targeted object is measured to estimate the distance.
An operational amplifier (Op-Amp), a variable resistor, an output LED, and an IR transmitter and receiver pair (also known as an opto-couple) make up an active infrared module. A power supply of either 3.3V or 5V with a maximum current of 20mA can be used.
Remote control uses IR rather frequently. If you have the appropriate decoder, you may use this IR receiver to send commands to the Arduino project from any IR remote controller.
By quickly turning on and off an infrared light source (transmitter), infrared data transfer can be accomplished. The infrared light flashes, and a receiver sensor [sees] it and converts it back into the original signal. Consider very quickly Morse Code.
Infrared networks function similarly to television remote controls in that they transfer data using infrared light waves, which are invisible light waves. While infrared (IR) networks function similarly to wireless networks, they use light waves in the infrared spectrum for data transmission and reception rather than radio waves.
Infrared heat is what we experience when we are near a fire, sunshine, radiator, or heated pavement.

There's not much to say—it performs as promised. Instructions for wiring were not included. The wiring, however, is rather clear: Light: +12V, Dark: -12V White and blue: no contacts. I've got it to switch a 12 volt relay. For an actual load to be switched, the wire is too light gauge. Notes: The blue pilot light is very bright. I had no trouble learning the IR codes for my Harmony control.

The popular Tandy Radio Shack "electronics kits" from my childhood have been largely replaced by R-Pi, Arduino, and Microbit. Basic R.Pi kits are readily available, but adding to them can quickly become very costly. This kit is a great all-in-one STEM kit upgrade, with modules costing about $5–$50 (some sensors, some buzzers, servos, etc.). Not all of the modules have been tested yet, but the ones we have (the majority) function flawlessly and as intended. Moreover, the storage case that comes with the package creates a very tidy package with no drawbacks. Excellent and strongly advised. This goes without saying if you're a parent looking to upgrade your child's R.Pi kit or if you run a STEM day camp for children.

Although I don't currently have the time to work on the project, it looks wonderful and is of excellent quality.
